How long you can stay China
The school will allow you to stay as long as you want. The problem is usually obtaining a visa from the Chinese embassy in your country. Going to China with a tourist visa is no problem. In most countries the Chinese embassies issue 90 day visas, but in some countries, you will only get a 30 day and one entry visa. Contact the next Chinese embassy for more info. Unfortunately the Song Jiang Wushu School doesn't have the required certificate to run an official student exchange program. So they are not able to help you achieve a student visa. Since a few years only some universities in big cities like Beijing and Shanghai have this privilege. For more related topics go to Learn Wushu in China Main.
