The moral of the snake shadow is that fear is caused by paranoia.

1, meaning: a glass of bow and snake shadow is a metaphor for being suspicious, disturbing oneself, taking untrue things seriously and forming fear. From the biography of Jin Yue Guang, it is a metaphor for fear caused by paranoia.

2. Fable story: One summer, the county magistrate invited Du Xuan, the official in charge of paperwork, to have a drink. The banquet was set in the hall with a red bow hanging on the north wall. Due to the refraction of light, the shadow of the bow is reflected on the glass. When Du Xuan saw it, he thought it was a snake crawling in the glass, and suddenly he was sweating.

3, but the county magistrate is his boss, and specially invited him to drink, so he didn't dare to drink, so he took a few sips. When the servant poured the wine again, he apologized and left. After returning home, Du Xuan became more and more suspicious that he had just drunk the wine with snakes. He felt that the snakes following the wine were crawling in his stomach. He feels unbearable pain in his chest and abdomen, and it is difficult to eat and drink water. The family quickly asked the doctor for treatment. But he took a lot of medicine and his condition still didn't get better.

A few days later, Chen Ying went to Du Xuan's house and asked him how he got sick. Du Xuan told me that there was a snake in his glass when he was drinking that day. Chen Ying comforted him and went home. He sat in the hall and thought over and over again, wondering why there was a snake in Du Xuan's cup.

Suddenly, the red bow on the north wall caught his attention. He immediately sat down where Du Xuan sat that day, picked up a glass of wine and put it in its original position. There was a bow in the glass. If you don't look carefully, it really looks like a snake crawling.

Chen Ying immediately ordered a carriage to pick up Du Xuan, let him sit in his original position, told him to observe the shadow in the glass carefully, and said, "The snake in the glass you mentioned is only the reflection of the bow on the wall, and there is nothing strange. Now you can rest assured! "

When Du Xuan found out what had happened, his doubts disappeared immediately, and his illness soon recovered.
