This fable has three main meanings. The first thing is to do things with an open mind, don't be paranoid without evidence, and dare to do things is what a gentleman does. The second is to be good at thinking and have the courage to discover.
The host asked the guests why they had not come after such a long separation:
Sitting in the front, someone gave me a drink, and I wanted to drink it. When I saw a snake in the cup, my intentions were very bad. When drinking, I think that "there are horns on the wall, lacquer painting is a snake" and "the snake in the cup is also a corner shadow". This is the reason why the guest is ill. To treat his illness, we must aim at this cause. So "put wine first", let the guests "feel at home", and then tell them the reason, let the guests understand their feelings and take control of their own illness.
From the source of the cup bow snake shadow:
1. Give it to the ancestor Chen as a souvenir, and ask the cashier to give wine in summer. At that time, a red crossbow hung on the north wall, which looked like a snake. I'm afraid of evil, but I dare not drink it.
2, pain in the chest and abdomen during the day will damage the diet, and it is not a cure to use dew to attack anything. Later, because of this incident, Chen went to Xuanjia to peek and asked him about his misfortune. He said, "You should be afraid of this snake, it will get into its stomach."
3, Chen is still listening, thinking for a long time, looking at the crossbow, it must be also. Then let the door bell down to wait on Xu Fu's chariot, and set wine in the old place, so there was a snake in the cup, because he said, "There is nothing strange on this wall." The announcement of the solution was embarrassing, so it was flat.
