How much regret does China have in immigrating to the United States?

In fact, foreign countries are not as beautiful as they think. Although many benefits abroad are free, such as medical treatment and good facilities, the wool is on the sheep. If you don't pay enough taxes and other expenses, you won't get such benefits at all. At the same time, many people abroad have a bad opinion of China people, and going abroad is not necessarily the best. Leaves fall to their roots, but people who go abroad always want to come back. Moreover, more and more foreigners yearn for China and begin to learn Chinese.
