As an university student , I want to know and learn more. Not only the knowledge I acquired from books , but also the culture in another country. I want to go abroad if I like the country's language, food, people' thoughts and so on. Most students who study abroad will come back someday. Even more most ABCs will come to China to carry on a trade. Because the market in China is big beyond your imagination. Thanks.

Simply because it's too crowded. Haven't you noticed that?

Lol, I'm sure a lot of people are tempted to bash China's communism here. I'm not in the best position to comment since I have never been there but here's what I believe. China's economy is doing well and it has a massive Balance of payments surplus and this, is largely owing to its yuan, which has long been an issue and recently been the subject of scrutiny of the Americans. The artificially low yuan creates more investments and stuff in the country since wages across the nation are generally much lower in comparison to other countries. To the average worker this means a lower income and hence lower purchasing power compared to a foreigner. Hence the only logical thing to do is to try and secure a job and citizenship abroad. I think this is one of many reasons but nonetheless it is a major reason deterring them from staying put.

Chinese point of view only? Ok, I will speak on their behalf: To plunder your country's resources and slowly own enough of your country to take it over! :P

Simply, some people want to escape the communist regime, and they find freedom in the West.
