For a country of 1.321,851,888 billion people, the Chinese government is rather persnickety about sex. What, they don't want to give people ideas?
Movies with sex scenes are banned in China. Not only that, their producers are banned from working for a specific number of years.
I know Lust, Caution was heavily censored. And people who include sex in their movies risk ruining their careers forever.
Recently, a famous young Hong Kong actor had to abandon his career because somebody posted some sexy photos he took of himself cavorting with female celebrities and now he is shamed and humiliated and will dedicate his life to good works and charity.
Imagine! He should move to Hollywood, where no amount of debasing behavior is ever enough to sink anybody.
