1. China's scientific research funds are too small, there is no focus, and the most important thing is that they cannot be turned into profits immediately.
2. European and American countries monopolize technology. They decide what to develop, not what we want to develop.
3. Although China claims to be the cleverest race after Jews, it actually has no advantage in evolution. In the case of similar intelligence, white people's height, physical strength and adrenaline (adventurous spirit) have left the yellow people far away.
4. Researchers are a marginal group in China. Few people can inspire the poor and spend their whole lives inventing something, and many scientists in the United States are also embarrassed. The youngest one who won the Nobel Prize is over 40 years old, and the oldest one is 89 years old. Most scholars in China are isolated, especially those persecuted by the older generation. It's really sad that they became X-pie. It is difficult for the professor to summon up the courage to continue his career.
Some things need people to "sacrifice", which is not the spirit of China people. At present, the gap between men and women in China is about 30 million, and there will be about1.500-1.8 million bachelors in the school-age population. In other words, since the implementation of family planning, China has probably killed nearly 20 million baby girls. This ancient nation has indelible bad habits. It's actually a joke that you talk about science with such a nation. It is ok to shout slogans.
