Not sure how do you define “useless”, but there are a few things you might find interesting:
1, Chinese women receive a month of special care after labor, what we call “坐月子”. You may call it a Intensive Care Unit at home. The new mother is not allowed to go out of the room, not even to take shower or eat icecream, just to avoid anything “cold”. She is fed with all sorts of nutricious food like chicken and pork among others all day long, to help her recover from the labor and also help her to produce enough breast milk for the newborn. It’s a bit oldfashioned for the new generations and lots of new mothers do not accept it. But there is still a strong tradition here.
2, Chinese love to hang some small ornaments in their cars. It could be a badge of Chairman Mao, or some articles of buddhism, or a Chinese knot. It doesn’t necessarilyi mean the driver is a Maoist or buddhist, it’s simply for best wishes of luck and safety.
3, Most Chinese people wear long underwear in winter to keep warm. Even in Southern part of China, where it belongs to subtropical area, it gets pretty cold in winter days. I know by Western standard it’s over protection, but why do you push yourself so hard when it makes you much more comfortable when putting on an extra layer? We just can’t imagine why women in Western countries wear skirts with bare legs in winter. Aren’t your feeling cold at all?
4, You know people in east Asia usually use chopsticks, but have you noticed any difference between the chopsticks of each of the three countries, China, Japan, and Korea? See below the picture:
You see Japanese chopsticks are shorter while Chinese ones are longer, and Korean are in between. And the Korean ones are usually metal, while Japanese and Chinese ones are made of wood. China uses bamboo too, and also the synthetic chopsticks are also getting popular.
5, As a Chinese man, I’m kind of surprised and baffled to find out that the typical faces of a Chinese woman in the eyes of the Western people look like this:
With slanted eyes and single eyelid, this type of face would not be liked by most Chinese men. Here is a face which a Chinese man would find beautiful:
