Yelin's college is rocket control, which is also the technology that China urgently needs. At the University of Cincinnati, Ye Lin was exposed to a lot of high technology, which was obviously needed by China. But no one thought that Ye Lin didn't go home after learning well.
However, who can't see his share? The people of China warmly welcome all biologists who love their motherland, but China never warmly welcomes people like Ye Lin. It was not the motherland that abandoned him, but he abandoned his motherland himself. Ye Lin is not without a choice. As a foreign student at public expense, he has already shouldered the hopes and obligations of the motherland, but chose to betray the motherland. The end result can only be said that he deserved it.
