When the maglev vehicle was first released, a well-known foreign company wanted to spend 50 million yuan to buy this patent, but Cai Yuchen directly refused, saying that it would leave the technology to the country. This is the patriotic talent who is willing to contribute to the development of China.
Cai Yuchen was very different from other girls when she was a child. Other girls like Barbie dolls and some lovely things, but Cai Yuchen likes science very much. She has read many biographies of scientists since she was a child, and also likes popular science books. In addition, Cai Yuchen prefers to practice by himself. Through what he saw and heard, Cai Yuchen gradually formed his own ideas. She got very good grades in science and liked reading some extracurricular science books, so she didn't spend much energy on her studies and gave her time to study what she was interested in.
After being admitted to Shanghai Jiaotong University, she still maintained her love for science. After the maglev train appeared, Cai Yuchen thought, since there can be maglev trains, why can't there be maglev cars? The maglev vehicle envisioned by Cai Yuchen can solve the emission problem without using gasoline, and it can also be unmanned. Cai Yuchen told her ideas to the teachers, who all felt very good and were very willing to give her guidance and help. The school also gave Cai Yuchen an opportunity to communicate and study in Paris Reno Studio.
Cai Yuchen spent two weeks making a model, so the world's first maglev car came out, and Cai Yuchen named it "upright". The upright appearance consists of two transparent bubbles. It looks like a big helmet without tires. It can move 360 degrees and is unmanned.
Cai Yuchen took it to participate in the Renault Automobile Design Competition and won the championship all the way. Later, Upright was exhibited in an exhibition in London. This time, many foreigners marveled at China's technology. Also this time, a German company took a fancy to this invention and proposed to spend 50 million yuan to buy a patent. Faced with 50 million yuan, Cai Yuchen never wavered, and decided to bring technology back to its own country, because in the world, having advanced technology means having the right to speak internationally.
Cai Yuchen's act of bringing his invention back to China greatly encouraged many talented young people and began to take an active part in the road of innovation. Before that, many young people with ideas thought that invention and innovation were useless. This time, Cai Yuchen's example made them understand that personal ideas can increase confidence in the country, so young people's enthusiasm for research and invention becomes stronger.
