Do you know why Chinese people start using chopsticks?
Chopsticks have been used since Zhou dynasty in 100 years B.C. In that period, only a few people had dining table because it was wasteful especially when the wood lacked or it was very difficult to find.
However, most Chinese food was needed to be dipped with soy sauce, that made people had dirty hands and fingers after the meal.
Therefore, Chinese people needed an equipment to help them to take their meals easily with one hand because they have to hold the plate in another hand.
Due to the fact that chopstick was made by less wood and less money, so they started using chopstick for holding food in order to have clean hands after the meal. ^^
