[English]
Hello, audience friends, I am Li Wenyi
Welcome to Taiwan New Ideas Today
We want to discuss the theme of today's episode with you
In the end, it is up to humans to build a sun
Is it possible
This scene looks like the plot of a science fiction novel
Now it is not only possible to achieve
The speed must also be accelerated
Look at this artificial sun on the screen
The proper noun is called nuclear fusion
In the most vernacular way,
it is composed of more than two atomic nuclei
combined into a new atomic nucleus
It is called the sun
because this 4.57 billion-year-old star
releases light and heat through nuclear fusion
Therefore, if human fusion is successful
we will have the first one in history
Inexhaustible energy
Because it relies on the isotope knife of seawater hydrogen
Just one reaction
can create 3.15 million joules of energy
Not only does it not emit carbon
, but it also only contains a small amount of low-level nuclear waste
In theory, just a small cup of fuel
can power a house for hundreds of years
Next, we will take you through the special topic to analyze
What secrets exist in nuclear fusion, which is known as the Holy Grail of energy
...
And how far humans have to go if they want to build a sun
...
Look up at the night sky
The dark universe is lit by countless stars
The sun is a perfect star
The light and heat it emits
Enough to last the earth for billions of years
The sun is very big, so it is very heavy
So it is equivalent to gravity holding all the particles
together
The core of the sun is as high as 400 million degrees
Up to 600 million tons of hydrogen undergo nuclear fusion every second
It can be said to be the most mysterious physical phenomenon
And is it possible for humans to realize the dream of nuclear fusion
Create an artificial sun
He Ronghe
is a major solution to the future of crystallized energy for mankind
In order to unravel the mystery behind the principle
we came to the Atomic Energy Commission to find experts
You can see this cement wall
We had calculated the radiation it produced
We need at least a 40 cm thick cement wall
to concentrate its radiation inside
In addition to the 40 cm thick cement wall
A 5 cm thick lead door was also built
The purpose is to prevent high-energy particles from ejecting outward
This is a nuclear fusion laboratory
The location is at the Nuclear Energy Research Institute of the Yuan Energy Association
And in the center of the room
is a small nuclear fusion reactor
The first step is to vacuum
and then pour the experimental gas I want into it
Then the next step is this capacitor bank
It needs to discharge to generate current
to generate a magnetic field
and then focus the plasma outside
and then produce a nuclear fusion reaction
As early as the 1960s after World War II,
the scientific community began to study nuclear fusion
Traditional nuclear power generation uses nuclear fission
to impact a large atom through neutrons
Split into two small atoms to release energy
But the process will produce a high concentration of
radioactive nuclear waste
The half-life of millions of years is still unsolved
This radiation is
Well, when we talk about the half-life, it is actually very long
So it just puts it there and it keeps radiating
There is always radiation energy coming out
The so-called nuclear fusion
It is to fuse two small balls into one big one
Most of them choose the isotopes of hydrogen, deuterium and tritium
The most difficult part is that both atoms are positively charged
and will repel each other
And for them to fuse to release energy
It is necessary to simulate the extremely high temperature and high pressure environment of the sun
And nuclear fusion will only produce low-order nuclear waste
It is regarded as the Holy Grail of energy
The product contains helium neutrons
Titanium is a neutron without radiation
In fact, it itself is also defined as a radiation
Then you can actually use cement to block it
...
Nuclear fusion has high energy efficiency
The energy released is millions of times that of chemical reactions
If you want to generate 1 billion watts of electricity
Thermal power plants consume 2.7 million tons of coal every year
Switch to nuclear fission
and consume 1,000 kilograms of uranium 235 every year
As for nuclear fusion
Only 250 kilograms of fuel can achieve the same power generation
And the deuterium in the fuel can be obtained from seawater
It will help to significantly reduce carbon emissions and delay climate change
This is why for decades
Countries are rushing to participate in the nuclear fusion competition
However, there is a famous saying in the field of nuclear fusion. If you want to realize it,
you will always have to wait for another 30 years
thirty years left and always will be
That is to say, if you asked me 30 years ago when will it be realized?
After 30 years, you ask me today when will it be realized
In fact, I will still tell you about twenty or thirty years later
Why do scientists say this
Because it is not that the nuclear fusion reaction has not been successful in the past 60 years
There have always been bottlenecks that need to be broken
The biggest hurdle is the output energy
It must be more than double the input energy
It was not until 2022 that this milestone was finally reached
The first time I spit out more energy than what I put in
Well, hey, so this is where it's very important
thank you to the NNSA
the national nuclear security administration
and everybody who has been involved in this fusion
breakthrough that will go down
in the history books
The one that successfully set a new record for nuclear fusion
is a national laboratory in California, USA
There is a US national laboratory inside
To put it bluntly
it is the largest and most powerful laser system in the world
main Laser operation will begin in approximately one minute
This system is as big as three football fields
There are two laser cabins
that can generate up to 192 laser pulses
three
two
one
High-energy and high-speed laser pulses are formed through amplifiers
How amazing the energy speed is
It only takes one second, which is 1/100,000 seconds
to complete a nuclear fusion reaction
Laser pulses simulate the interior of the sun
With a high temperature of more than 100 million degrees
and a high pressure of 1,000 times atmospheric pressure
the fuel ball implodes to achieve nuclear fusion
The original promoter of the laboratory
was Edward Teller, known as the father of the hydrogen bomb. At this stage
...
...
...
...
...
...
...
is the artificial sun finally coming true?
Taking this laboratory in California as an example
a total of 2.05 million joules of energy was input
and 3.15 million joules of energy was produced
Although the net energy gain was 1.5 times
but in order to generate the laser pulse
it actually consumed up to 322 million joules of energy
Just getting even is useless
Then usually everyone's goal should be about 10
It is to throw out 10 times the energy
The reason is that this energy will be converted into electricity later
This conversion to electricity will consume some energy
Net energy increase
It must be at least 10 times more to have power generation benefits
In addition to finding ways to reduce energy consumption
Nuclear fusion must continue
Experts admit that there are still many challenges in food
Send the pill to the location
Then you have to exit after it is lit
Another one has to come in
Oh, it’s him
In terms of mechanical design
That may be a big challenge
Most of the goals of new startups are set in 2035
2030-2035 to generate energy
Despite the difficulties
scientists have never given up
Just like a million years ago
humans first learned to drill wood to make fire
Open a new page in historical development
Once the
dream of artificial sun is realized
it means that a new era of unlimited energy is coming
But in this new battlefield
Is there any chance for Taiwan to rise
In fact, Taiwan not only has opportunities
but may even become the first country in the world
to commercialize nuclear fusion technology
Different from large-scale nuclear fusion reactors
, what Taiwan does
is mainly based on small desktop nuclear fusion systems
As early as August 2021
it has achieved a net energy gain rate of more than 100%
It has been able to operate continuously for more than 8 hours
You can see the reaction inside
It will glow
Inside the transparent glass container is a group of blue-purple light
Constantly emitting lightning
Known as the most advanced small nuclear fusion system
Appeared in Taiwan
It can run continuously for 8 hours
At the beginning
If you mess with it, it will not be very stable
Yes, then after about 40 seconds
well, he became very stable.
This is a Taiwan-US joint development
Desktop fusion device
The size is only the size of a computer host
It can be used in the office or even at home
Compared with European and American countries that have invested in
ultra-large nuclear fusion
Taiwan chose to develop a small system
Focusing on the advantage of low cost and fast R&D
For desktop type
First, we do not need so much R&D funds
We need to be very fast
We can do many experiments
That experiment may cost hundreds of dollars
Thousands of dollars
In this way, after his reaction
he will not produce
Generally the problem of neutron radiation we just talked about
So its volume can be reduced
There should be no need to consider radiation
Do some radiation shielding
But relatively speaking
that is to say
the temperature of the reaction will be relatively high
Maintain a vacuum inside the reactor
put in hydrogen and boron and energize it to form a plasma state
to perform nuclear fusion
Compared with the reaction of deuterium and tritium
it can avoid radiation and nuclear waste
Especially hydrogen is the main element of solar nuclear fusion
The problem is that it requires energy of 30,000 to 100,000 electron volts.
The general laboratory voltage is about 500 volts.
How to do it?
Lightning can reach
about 60,000 to 70,000 million electron volts.
Then we also use lightning. Successful creation of fusion reaction
...
...
...
...
This set of desktop fusion
is ready to start commercialization this year
The fastest commercialization is 2027
By 2027, we hope to be
By 5 times
You are basically like a sun
That means that after I started to ignite it
he will generate energy by himself
Under the goal of net zero carbon emissions
Thermal power generation and traditional nuclear power plants
will go into history in the future
Replaced by rate energy
But the biggest disadvantage of renewable energy is that it is intermittent
and cannot provide stable power supply
Once nuclear fusion operates stably
it can continue to produce clean energy
Take this small device in Taiwan
The net energy gain rate can currently reach 1.2-1.5 times
It is expected to be used to generate steam for the petrochemical industry
The output power target in the first stage is 1,000-10,000 watts
The net energy gain rate in the next stage will be 3-5 times
The output power is 10,000 to 50 megawatts
It will be able to load electric vehicles and factories
For large systems developed by other countries
The output power will reach more than 50 megawatts
Only in order to become the power generation host of the power company
In Taiwan alone, the US dollar is probably ah
500 million to 1 billion yuan
This is a trillion-dollar industry
If this technology can really develop it
then this business opportunity is very, very big
There is no doubt that nuclear fusion is energy
In the future, it will be the next number one industry
It is a pity
There were not many talents in the field of nuclear fusion in Taiwan in the past.
Enterprises want to accelerate research and development.
The first challenge is to find people.
He said it is not possible now.
...
...
...
...
...
In fact, nuclear fusion is an interdisciplinary science
spanning plasma engineering, magnetic field devices, superconductors, etc.
Different majors
But currently Taiwanese talents are scattered in different industries
Even scholars and experts who specialize in research are very few
We have this course
but we may not be able to find suitable professors at the moment
Like our
graduation review form
There is a course called Nuclear Energy
But there is no such course at the moment
This is why I came to the Institute of Plasma
Once the nuclear fusion industry is formed
it can accelerate the pace of development
The National Science Council and the National Energy Council began to cooperate
They will imitate the multinational nuclear fusion reactor ITAR
Create a Taiwanese version of Tokmak to achieve military training
We will do some things in the two-year plan
Some simulation designs of tokemar
The plan is to build a small tokemar in the third or fourth year
...
It is for teaching and research
I hope to use this tokemar setting
to establish some educational talents in Taiwan
A giant ring-shaped superconducting magnet
can form a nuclear fusion environment through a strong magnetic field
But the ITAR cost is as high as NT$600-700 billion
The current domestic planning budget is up to NT$45 million a year
The scale gap is huge
But it is already a big step for Taiwan to develop nuclear fusion
You have to have a goal to be attractive
Today we can increase the coefficient
We can publicize that we are going to do nuclear fusion
When students come, it is good to be the first
Then if I do this, where will I go after graduation
When you have no future job opportunities
It is difficult for you to attract the people behind you
Each university should put 10 to 15 units
You can start learning this nuclear fusion right now
You can do experiments for college students
Facing Taiwan's talent dilemma
Enterprises are also developing small experimental machines
Hope to provide research units with use
Accelerate the realization of the technological dream of artificial sun
On July 14, 2023
Taiwan's first self-made weather satellite Wind Hunter
was shipped to French Guyana
It is expected to be launched in September
If successfully launched
this satellite
will be able to provide nearly 70,000 pieces of data every day
making Taiwan a key international exporter of
meteorological data
And there is an important person
that is Director of the National Space Center Wu Zongxin
In fact, many people are familiar with him
He is Taiwan's most famous rocket, Abei
In the past, he successfully launched the first
large-scale hybrid sounding rocket in Taiwan's academic community
He is also the passionate Abei in the Mayday MV
who never gives up
Now he is Taiwan's hope for advancing in space
And this episode's exclusive interview with the great figure Wu Zongxin
will show you how he leads Taiwan
Leaving the surface of the earth
Heading for Space
2004
An American high school student with a height of only 168 cm
rewrote the rules of basketball around the world
He was laughed at at the time for looking like a child
Now he is the greatest shooter in NBA history
Rush, rush, otherwise how can I do so many things
1984 A college entrance examination failed
Twice unemployed
A down-and-out man who has been supported by his wife at home for 6 years
Unexpectedly, a planet in the future
will be named after him
He is the only Asian director in history
Ang Lee who has won two Oscars
A big problem for students in Taiwan is that
very few take the initiative
He can feel it if you do well in exams
Only classmates or teachers will like him
So you can lie to me no matter what you say
Wu Zongxin, the most famous Rocket Abei in Taiwan
The first speaker in the history of TED to explain professional technology in Taiwanese
...
How to build a bridge to the universe for Taiwan
Rocket Abei is a guest at the big man's hot-blooded opening
Those who dare to dream are welcome to sign up.
I've been to spaceX and they have this kind of thing
It's true
spaceX
They use this in their
Companies all have this
And this spaceboy is so cute
In fact, I see your experience
You actually never thought you would go into space
No this, no this
So a lot of things
Yes, but I have some central ideas.
For example, I want to do
something that is more influential in Taiwan.
Well, it has an impact.
As a teacher, you have written a paper. Wu Zongxin, who is almost 60 years old
...
...
...
...
...
...
The crisis of making middle-aged people gain weight
passed him by
In the past, he always said that he was 195 centimeters
However, in fact, it was far less than this number
And he only weighed more than 50 kilograms
However, his plans and ambitions were very ambitious
He said that he had never thought about going into space
He didn't expect that the next step would be to go to the sky
It was so big that he himself said it was like a child playing with a big car
But looking back at Wu Zongxin's experience
you will know that he is serious
He went to Nanyizhong University in high school and got his master's degree in National Taiwan University in Mechanical Engineering
After graduation, he got a scholarship
Go to the University of Michigan to study for a doctorate in aerospace engineering
An overly beautiful academic qualification
It is unimaginable that he actually came from rural Tainan
His parents were illiterate at all
1964 was the year Wu Zongxin was born
...
Taiwan began to accumulate foreign exchange
It was about to move from the agricultural era to an industrial society
At that time, Wu Zongxin had 6 children in his family
He was the youngest
Both parents were doing hard work
There is a problem wherever the next meal is
As for space
To the Taiwanese at that time,
was just the background of science fiction movies
Not to mention
That was Wu Zongxin who couldn't even drink milk
In fact, our country's Xiao Zhen's wish was to become a national baseball player
Because that elementary school is
The third generation of the Tainan City Giants
There is another childhood dream for survival
That is, eating was the most important at that time
However, after entering the elementary school
Wu Zongxin discovered
Because of the parallel time and space created by poverty
In addition to life
There is also language
I spoke Mandarin in the first grade
So I couldn't understand it at all
Because I
Even though I was born and went to elementary school, I was stupid
I couldn't understand what the teacher said
I was deeply impressed by the second grade
I got second place in the final exam
When I think back, my sister said
It should be then that I understood Mandarin
But when he grew up, Wu Zongxin did not lose Taiwanese
Instead, carry it forward
Go to the United States to study and insist on speaking Taiwanese
At the 2016 Sanli Taiwan True Hero Award Ceremony
He also used Taiwanese
Reflecting his ambition for the world
I am absolutely confident
We are absolutely confident to overcome the mountains ahead one after another
We must overcome this difficulty
I must leave the earth
Will not give up
Want to shoot the Taiwanese's space dream
The Taiwanese's dream into the boundless space
Come on Taiwan
Thank you rocket team
Go ahead
Otherwise it is impossible
How is it possible to do so many things
If you can finish it in 10 minutes
Why do you have to do it in 20 minutes
August 2, 2021
Wu Zongxin has changed from a distinguished professor
to the director of the National Space Center
He is responsible for
Taiwan’s entire space dream
But the reality is that in the year he took office
the space center’s budget was only NT$2.5 billion
As for South Korea’s budget in the same year, it was NT$14.9 billion
There are probably four parts in the general space industry
One is
rockets and satellites
and some control on the ground
related receiving devices
The other one is applications and value-added services
So you can dig into its content
It means manned but not manned
If it wants to carry people, the investment cost will be terrible
So there are actually few places in the world
namely the United States, Russia, China
Because the things that go up are very expensive
One kilogram
If it is sent to orbit, it may cost tens of thousands of dollars
Oh
Yes, there is also a satellite that may be
1 billion 2 billion 3 billion
Ah, beautiful!
July 10, 2022
Taiwan's first hybrid satellite-like carrier rocket
was successfully launched from the Xuhai Launch Site
It fell into the sea two minutes after takeoff
The actual flight altitude was 3 kilometers
Maybe it was too small to carry people
Maybe the achievement seemed insignificant
But it was the world's first
hybrid rocket with guidance and control technology
It took Wu Zongxin nearly 20 years to get here
Because space is different from the ground
As long as he goes up
there is nothing you can do
Like a car that breaks down, it can be recalled
Another more important thing is that he has cosmic rays
including α β γ
If you don’t have a strong IC manufacturing industry
In fact, there is nothing you can do
Make these anti-radiation lenses
This one
Put it inside. This is an aircraft
Sorry, it’s a flying body
Could you please take it off
Pick it up and wait a minute
This is the scene of Wu Zongxin appearing in front of the media for the first time in 2015
At that time, he
...
was not the Rocket Uncle in Mayday’s stubborn MV
Just a down-and-out professor with a group of nearly 30-year-old students
who could not receive subsidies
At that time, they
had been working on rockets until they could no longer survive
Nearly 70 million
And now we have bottomed out
In the middle, we actually fought for it so that we could continue
and let it go
Then the youth of students
The teacher's youth is gone
After five or six years, wow, you won't do it
I think this is
For me personally and for the students
I think it is a joke
In fact, this is not bad at making fun of him
At that time, compared with the rockets that the astronauts rode
Wu Zongxin's team was not big enough and could not give it away
They are often ridiculed for playing soaring cannons
But what you don’t know is that
without state subsidies
each test launch is the most basic cost
and costs 100,000 yuan
Wu Zongxin was once in debt of 600,000 to 700,000 yuan
So in order to make money,
he launched the first fund-raising operation in the name of a rocket in Taiwan's history
...
This year he went all over Taiwan to give speeches
Constructing rockets to push the space economy
At this time
He became the first speaker in the history of TED
to explain professional technology in Taiwanese
The future of middle-aged Aber
In fact, I want to do my best
I have almost 20 or 30 years of struggle left
Maybe not to create a bright future for Taiwan
This is our wish Finally, I want to announce to everyone
We will never give up
Just leave the earth, thank you, thank you
I have a personality, I love a group of people to do things together
Yes, isn't that what rugby is like
...
Yes, yes, I used to play baseball and basketball
It was just a bunch of people playing basketball and bullfighting
Or in a mess
When the ball comes out, I get it myself
But you are the concept of the brain
I decide how I want to attack
At some moments, I feel like Wu Zongxin is like a child
But maybe because
this boyish atmosphere
reminds me of myself from the beginning of society to the present
I don’t know how many companies I have changed
How many colleagues have come and gone
Life is still going on
It’s not that I don’t dare to think of dreams
But we are living in an era of choosing only good things
Not willing or courageous to face bad things
A big problem among Taiwanese students is
Very few take the initiative
This is related to Taiwan’s education system
Why is it because of your elementary school kindergarten
Even if your elementary school grades are not good, it is actually OK
Yes
Unless you spend most of your time playing or at home
But when you go to junior high school or high school, it doesn’t matter whether you have money or not
Just work hard and take the exam
It’s the exam
If you are a child, he will notice
My performance in school is not good
Do you pay equal attention to the five virtues
(Full marks are important)
He can feel it if you are good at exams
Only among classmates or teachers will like him
So he thinks you are lying to me in everything you say.
You are lying to me in everything you say with beautiful pictures.
So we are like a good school in Jiaotong University.
You will find out how that child
became like this. But from him
...
...
...
...
...
I feel that actually
maybe as long as you do one thing well in your life
your life will be complete.
From him
I will also reflect on myself
When encountering difficulties
Do you choose to turn around at the first time
Give up
But sometimes you don’t insist on going on with many things
You don’t know the final result
What will it look like
Please unveil
The others are some that have been launched before
But these are all foreigners
There is only this one
It looks thinner
We did this ten years ago
There is probably no accident
In the future, Taiwan will have its own satellite vehicle
He will make you more excited than the satellite looks
End of interview
I asked him if Taiwan really had a chance
Can he have his own rocket?
He told me to wait and see his performance next year
His tone still revealed the aura of a passionate boy
It seems that even though he changed from engineering clothes to a suit
, the soul of
Rocket Uncle has not dissipated
He once watched the rocket take off
Then the scene of a bunch of scientists hugging each other and crying
is far away from us
But maybe now we can really bravely dream
and even touch the distant future that Taiwan
cannot touch
Mentioning the space field
One of the industrial chains is drones
2016 is the time when drones began to rise
And the nutrients for his growth
come from the widespread application of space satellites
Especially DJI from Shenzhen, China
Known as the iPhone of the drone industry
The global market share exceeds 70%
Even Taiwan's government agencies
almost exclusively adopted it in the past
But in 2020
Because it involved information security and national defense concerns
DJI was blacklisted by the United States
At the same time, it also withdrew from the Russian and Ukrainian markets
So this trillion-dollar UAV market
may be a new blue ocean where Taiwan can flex its muscles
Next, we will give you an in-depth analysis
Whether Taiwanese manufacturers can seize the opportunity and take advantage of the trend
Alishan, Chiayi, composed of mountains, seas and plains
The sunrise shines on Alishan
The gorgeous sun rises slowly
As many as 600 drones show up in the night sky
Taiwan’s famous Alishan sunrise
The image that appears now is Taiwan
Rotate while constantly changing graphics
From 3D Taiwan to the rotating Earth
You can even write calligraphy in the air
Taiwan's drone performance technology continues to evolve
But the R&D team has embarked on new breakthroughs
After completing the development of these performance technologies
We are now further advanced into this
It is more of a real-time calculation and operation
Changing formation
Large-scale drone demonstrations require accurate route control
Although the difficulty is high
but it can be overcome through time planning
The next step is to combine the AI algorithm
to allow the drone swarm to automatically change the formation in time
Good swarm is ready to take off 32
10 drones take off at the same time
Good next move
From a simple array to a triangle
Show other geometric shapes
In the future, these commercial drones
will not only be able to communicate in the air
and even take the initiative to give commands
The application level will also be expanded from Zhanyan
to blanket defense and search
There is a host in the sky that allows it to carry 100 wingmen
He can command
These 100 wingmen themselves must have some autonomy
Then we need to calculate and communicate with each other
Then the thing about avoiding waves will involve
That is to say, uh, the number of my aircraft
In addition to the calculation, uh, the quality of communication, etc.
At present, we will first achieve 50 aircraft
In the future, we hope to increase it to 100 aircraft
or even higher
When a major disaster occurs
Drones can be dispatched to deliver supplies at the first time
Or to deliver packages to remote areas
It can also be equipped with network devices
to help restore communications in disaster areas
and obtain high-resolution images for disaster response
When Kaohsiung was hit by gas
That was the first time Taiwan's drones came into play
He covered the entire Kaohsiung in just one day
...
The situation in this disaster area was very, very tragic
Do very precise shooting like this
The application level of drones continues to expand
Statistics from the Ministry of Economic Affairs
The global market size in 2022 will be approximately US$30.4 billion
It is estimated to grow to US$41.3 billion in 2026
According to the 2021 market survey
Global commercial drones
China's DJI has the highest market share
Up to more than 50%
Far more than the second-ranked American brand
However, with the sanctions on DJI
it will be Taiwan's biggest opportunity to develop drones
This drone manufacturer headquartered in Taichung
is a member of the national team
Three-story factory
From drone structural design to assembly and manufacturing
Everything is done
What our engineers are designing is what we will do this year
It is expected that this year
a helicopter under 25 kilograms will be commercialized
So this is a secret weapon for us
It is currently a secret weapon
We now need to take a look at the battery
Arrangement method
How to arrange it will be more appropriate
You can judge from this 3D picture
The appearance is like a small boarding case
This is a ground operation station developed by the industry
It has complete functions from route planning to flight settings
You can also see the real-time feedback screen
It mainly looks at some information about your aircraft
and then plans your route
Because how you want to fly is set from
here
What the staff is assembling
is the key component of the drone
It is mainly used to control the direction of the motor.
Just this small part
needs to be tested at least 100,000 times
to ensure the stability of flight quality
However, many domestic drone manufacturers
are still in the early stage of small and medium-sized enterprises
For this industry, the team is less than 20 people
But a drone is created from scratch
The development cost is tens of millions
The capital is only 9 million
In the first three years before the company was established
At that time, if we
had to integrate all these sub-systems
completely
the cost of development
would probably be a part of the company's capital
Taiwan's domestic demand market is small
A few government procurement cases
are already the largest layoffs in the country
It is even more difficult to compete with large international companies.
Only by constantly trying to find export opportunities
can they open up the international market
Today's Taiwan New Silk Road Thank you for watching
See you next time
