The first story is about Jiang Ziya. Jiang Ziya likes fishing very much, but he fishes with a straight hook every day, so he never catches any fish. Jiang Ziya's wife is very angry. One day, Jiang Ziya went fishing again and went home. He was so hungry that he wanted to reach for the meat on the table. As a result, a bird has been pecking at his hand at this time. He drove the bird away, and the bird came back to peck at his hand, but he was not allowed to eat meat with his hands.
Just when Jiang Ziya was about to get angry, the bird suddenly spoke. It asked Jiang Ziya to follow it under the fence, and then asked Jiang Ziya to grab two sticks to eat meat. When Jiang Ziya clamped the meat with a bamboo stick, the bamboo stick smoked. He felt very strange and asked his wife, who was so angry that she poisoned the meat.
After Jiang Ziya found out, he took these two bamboo sticks with him when he was eating, just to prevent someone from poisoning himself when he was eating. Later, people began to call these two bamboo sticks chopsticks.
The second story is about Dayu, and the chopsticks here can also be said to be the original form of chopsticks.
It is said that when Dayu was harnessing water, he passed the house three times and didn't go in. In order to catch up with time, he often eats three meals. Every time he eats in the wild, he is in a hurry. Because time is very tight, he rushes to eat every time he just boils. Sometimes the dishes in the pot have just been opened, so it is impossible to catch them and eat them. So for convenience, he broke two branches and picked them out to eat. Later, everyone saw that it was convenient and clean to eat like this, and they all began to get used to eating with bamboo sticks.
In fact, there are many customs about chopsticks. For example, chopsticks must be placed neatly on the table, neither too long nor too short. And when using chopsticks, never knock on the bowl with chopsticks, which is very impolite. And don't point at others with chopsticks when you speak, which is also impolite.
