There is a story like this. There is a kind of bird called an owl, and another kind of bird called a dove. One day, the dove met the owl and asked where it was going. The owl said that because the people here hated its cry, it was migrating to the east. Jiu revealed the secret: "You'd better change your cry, otherwise the people there will hate your cry when you go to the east." This story actually says that when a person has a fatal shortcoming, and this shortcoming is unfortunately discovered by others, what this person should do is not to change the surrounding environment, but to work hard to correct the shortcoming.
