A simple fact check will tell you it is illegal in China.
Legalized Incest Laws and Habitual Incest Practices are two different issues.
Irony is those "legal" countries have the fewest Incest Cases while those "illegal" countries are rampage when come to Incest. Guess they have to make it illegal before it becomes a norm in these societies. They have to keep reminding themselves it is illegal to fuck his own daughters, sisters and mothers. However, they think otherwise. Looks like Laws is difficult to implement on them.
What a sick Race.
