Here is summary of the laws I've found on another forum:
" China's Television and Media Committee recently released the following guidelines for things that should be discouraged from showing. They are all extremely vague.
（一）不符合国情和社会制度，有损国家形象，危害国家统一和社会稳定
Don't show unlawful stuff or things that threaten social stability.
（二）有损民族团结
Don't show stuff that promotes minority conflicts.
（三）违背国家宗教政策
Don't preach weird religions and cults.
（四）宣扬封建迷信，违背科学精神
Don't preach superstition and fake science.
（五）渲染恐怖暴力，展示丑恶行为，甚至可能诱发犯罪
Don't show excessive violence or entice people to commit crimes.
（六）渲染淫秽色情和庸俗低级趣味
Don't show sexually deviant stuff.
（七）侮辱或者诽谤他人
Don't commit libel.
（八）歪曲贬低民族优秀文化传统
Don't show racist stereotypes about minorities.
（九）危害社会公德，对未成年人造成不良影响的
Don't show stuff that's harmful to kids.
Of these, there's some debate on number 6, and what constitutes as "sexual deviancy". Though the government has never, and probably will never, out-and-out say officially that homosexuality is included as a sexual deviancy, people will assume it, and various politicians will support it.
But censorship isn't as well enforced as people think it is in China - and the Television and Media Committee alone doesn't have the right to pull a show off the screen, they need to go through a legal process to determine if the show actually violated various terms.
As an example, rule number 4 technically bans all depiction of ghosts and monsters, but Japanese-style ringu movies are still very popular in China. "
