Liang, there is a site called ICMag that has sections with other languages. Unfortunately since the penalites in China are so harsh, that site does not even have a Chinese-language section. Do you speak any other languages? They do have a Japanese language section which may be found here:

International Cannagraphic Magazine Forums - Japanese
Maybe you can find someone there who speaks your language.

I usually tell people that they can learn everything they need right here, but if you are looking for someone who speaks Chinese then you may have to look very hard.

There is a link in my signature that is written in simple terms that I hope you can understand, and also on YouTube there are some videos about growing if you are more comfortable with spoken English.

Best of luck, and STAY SAFE. Jerry Garcia is correct- there is extensive monitoring of internet activity in China that may put you in grave danger for visiting sites that are on 'the list'. I think maybe it is best that you concentrate on other, legal types of gardening, which can also be very rewarding, until you feel comfortable enough growing plants that you will not have to spend time on the internet. Do you have any relatives who have a vegetable garden and would like your help with it? That is a very good way to learn how to grow plants of all kinds.
