A long time ago, there was a learned scholar in the cold north. He wrote many books and people respected him. Ask him if they don't understand anything. He is willing to help others. On one occasion, he went to the south to solve a complicated problem at the request of the people in the south. That place is so hot, the sun is like a big fireball, and the houses and streets are going to smoke. Scholars can't stand the heat and have to work after sunset. One night, the scholar was thinking at the window. He suddenly found his own shadow standing on the balcony of the opposite room, as if to enter the opposite room. He knew it was from candlelight. For the first time, he was obviously surprised by his own shadow. The next day, he found his shadow gone. He was surprised and looked everywhere, but he couldn't find it. He wondered, "Didn't the shadow stay in that room all the time last night and didn't come out?" That night, the scholar stood at the window and looked across the balcony, but the shadow did not appear. The scholar doesn't know what to do. He thought: Without shadow, people will talk about me and think that I am an abnormal person. People will misunderstand me and alienate me. The scholar waited anxiously for several days, but the shadow still didn't come back. He solved the problem in a hurry and went home. People are shut out, immersed in research work and almost isolated from society. People are strange. They all thought that he had encountered some problems and left him alone. One day, the scholar heard someone knocking at the door, opened the door and saw a man standing outside the door who looked like himself. Confused, he asked the man, "Who are you looking for?" "You don't know me?" The scholar looked at it carefully, but still shook his head and said, "No" "I am your shadow!" The man said. The scholar opened his eyes wide and asked, "Where have you been hiding? I can't find you anywhere. How can you talk? " The man said, "When I was in the south, I walked into the room opposite your house." "Is there anyone in that room?" "A fairy used magic to show me many things that people can't see. I know the inside story of many things. There are too many evils and illusions in this world, and I am much more awake than when I followed you. " The scholar asked, "Are you going back this time?" The man said, "I have seen too many inside stories and too many illusions." I must make everything public and let more people know the truth. " However, I am a shadow, and many things can't be done. I must become a real person to finish this task. "The scholar asked," Then how can you become a real person? "The man said," there is only one way, that is, please condescend to be my shadow. Because a real person can't live without a shadow. " The scholar said, "That won't do! You are my shadow, why should I be your shadow? " The shadow begged, said sincerely and reasonably, which made scholars have to agree. As a result, the shadow became a scholar, and the scholar became the shadow of the shadow. After the shadow became a scholar, his attitude changed a hundred and eighty degrees. He didn't want to uphold justice and blew the whistle. The scholar who turned into a shadow said to him, "You should perform your duties. Since you know so many dark things, you should boldly expose them. "Cheng Ziyin said," I can't tell the truth, so I will lose my position and interests. I must remain silent, like a real scholar. " The scholar who turned into a shadow sighed and stopped talking, as if he understood something.
