Panic about the shadow of the bow in the cup-fear of the shadow

One day, Le Guang invited his friends to drink in the hall at home. When that friend was drinking, he suddenly saw the shadow of a small snake shaking in his glass. He was disgusted, but he drank the wine anyway. I feel uncomfortable and uneasy after drinking it. I got sick when I got home.

A few days later, Le Guang heard the news that his friend was ill and knew the reason why he was ill. Le Guang thought, "There will never be a snake in the glass!" So he ran to the place where he was drinking that day. It turns out that there is a colorful bow on the wall of the hall. The shadow of the bow happened to fall where his friend put down his glass, so Yue Guang ran to his friend and explained the reason. After the man understood the reason, he immediately recovered.
