That’s right, because research work requires a large number of technical talents, and China just lacks talents. It’s not that China doesn’t have talents, but that there is a brain drain. The main reason is that China’s social security is not good, and it cannot retain those people. When it comes to high-tech talents, there used to be a saying that "those who build atomic bombs are not as good as those who buy eggs." When China was building the atomic bomb, China was very poor, and all the funds were used for research. The wages paid to researchers were very small, and those who bought eggs were not as good as those who built them. In this way, the livelihood of researchers has become a problem, and the treatment abroad is very good and the salary is very high, so these talents go abroad. This is a real problem and has nothing to do with patriotism. Everyone has to eat. How can you live without money? ? If it were you, you would definitely choose this way.
