This doesn't mean you have to know everything about them before you talk to them.
Sex isn't always an easy topic to discuss with teens, but if your teenager is or might be sexually active, it is important for them to understand how different the expectations about sex are likely to be in China than at home.
If work or extended travel takes your family to China, it is important to have a working knowledge of Chinese customs and how these customs differ from American customs.
This is especially important if you have teenage kids, because Chinese dating and marriage customs can be very different from those in the U. American teenagers are used to a dating culture where neither partner usually considers marriage until both partners are much older.
For instance, some members of the Moniba ethnic group still follow customs where one woman is married to two or more men.
Most ethnic minority groups in China do not traditionally date or marry outside their own group, but be aware that social rules can differ.
Similarly, a girl who goes out for dinner with a Chinese boy and offers to pay for his meal or "go Dutch" could be viewed unfavorably.
