Why do many people want to immigrate to Europe and America, but few people think of China?

Economic factors are the main reason for immigration, which is the main motivation of international immigration. Not only China, but also other developing countries. China is not the poorest country, so people from other developing countries will emigrate to China, such as Viet Nam, Myanmar and even African countries.

For example, the largest source of immigrants in the United States is Mexico, which is a developing country and the United States is a developed country, so Mexicans are the first choice, while Americans rarely think of immigrating to Mexico.
