YUAN Zhuojian (Los Angeles commentator): The National Aeronautics and Space Administration (NASA) has gathered the world's top scientists, not only from China, but also from India. China scientists seem to be playing an increasingly important role in it, because his proportion is getting higher and higher. As we all know, being able to enter NASA is not only an academic recognition, but also an honor. This time, we can see on TV that there is another China person whose position is quite important. He is constantly giving orders, so it also shows that the reason why the United States can keep a leading position in these scientific and technological experiments is closely related to the top scientists he has absorbed from all over the world, as can be seen from the performance of NASA.
