If you have foreign friends with their little Baby, don't, and China, in the past and he touched the child's head, said as he touched the cute. Most foreigners don't like it. Have such a habit, I know that China also have such traditional, saw my friend's lovely child, just like the past hug, kiss, touch head in the past. In a foreign country, it really is to let each other off. Because they don't know whether you have infectious diseases, what touched before, what kind of bacteria. As a result, they will be particularly to protect their children.
