Early in Xia Dynasty (21st - 16th century BC), the shape of chopstick was still in development. Chopsticks only became two sticks of the same length in the Shang Dynasty (16th - 11th century BC). In the late Shang Dynasty, the tyrannical King Zhou ordered his craftsmen to make chopsticks from elephants' teeth, which was seen to be the most luxurious chopsticks in the early history of Chinese food culture.

First, don't use chopsticks to hit the side of your bowl or plate to make a lot of noise, because Chinese people think only beggars would do this to beg food. Second, when you use chopsticks, don't stretch out your index finger, which would be regarded as a kind of accusation to others. Never use chopsticks to point at others. Third, it is thought to be an impolite behavior when you suck the end of a chopstick. People will think you lack family education. Fourth, don't use chopsticks to poke at every dish without knowing what your want. And last, don't insert chopsticks vertically into the food. Chinese people do this only when they burn incense to sacrifice the dead.
