The first argument is that in ancient times, in order to control water, Dayu went home three times and didn't go in. He looks for food in the wild every day, sometimes in a hurry. In order to catch up with the time, he began to eat cooked food as soon as he boiled the pot. Because the food cooked at a high temperature was too hot to be held by hand, Dayu picked it up with branches and ate it, which was the cone of chopsticks.
The second argument is that Shang Zhouwang was emotionally unstable and very picky about food. One minute he thinks it's hot, and the next he thinks it's cold. Once da ji tasted a few bowls of dishes that were too hot to change, and Zhou Wang had already served them. Then da ji came up with an idea. He took two hostas from his head and gave them to Zhou Wang. In the process of picking vegetables, da ji kept blowing for him to pick vegetables, so the food was not so hot in Zhou Wang's mouth. Zhou Wang thought this method was very romantic, so she specially asked someone to make a pair of jade chopsticks for da ji and let da ji feed him every day.
The third argument is that after Jiang Ziya got married, he did nothing but fish every day. His wife thought there was no way to live like this, so she wanted to poison him. One day, Jiang Ziya went home empty-handed and caught nothing. As a result, when he wanted to eat meat, a bird came to peck him and wouldn't let him eat it. He talked to Jiang Ziya, not with his hands, but also showed his feet to Jiang Ziya. Jiang Ziya listened to the bird's advice and went back to get two silk and bamboo with meat. Then he picked up the meat and found silk and bamboo smoking white smoke. Only then did she know that meat was poisonous, so he always ate it with silk and bamboo.
