Why are fewer people studying in France?

After returning from studying in France, I worked in a domestic study agency for one year and met many parents who came to consult. I think many people give up studying in France for the following reasons:

1) small language, need to study in China, French exam with interview.

2) France is not an immigrant country, so some students want to stay abroad for a long time and bring their families with them, which is impossible.

3) The threshold is high, because it is a tuition-free country, and it is necessary to take the college entrance examination in China. There is a formal university admission notice, and the college entrance examination is preferably above 400 points. Students studying in universities in China should apply for French universities, and it is best to connect professional courses. Some people may think this is nothing, but there are all kinds of people going abroad, and many people are stuck in this one.

4) quite a few people go abroad to improve their lives, not really to study. France is not a country that gets rich quickly, so more people choose Japan, America, Britain and so on.

5) Highly educated people prefer the United States. The diploma is more valuable, and it is in English, so it doesn't need to be re-adapted.
