When you succeed, many people will care about you, but when you lose everything, there is no one around you; There are peaks and valleys in a person's life. Many people will take different attitudes towards you in different positions. Because everyone has a side of chasing fame and fortune and following the trend. This is the cold side of human feelings and things. But some people will be with you. There are also some people who are willing to help you, which is the cold and warm side of human feelings. When you are in power, there are plenty of horses and chariots, and when you are frustrated, there are few doors. This is the human sentiment is cold and warm, and the world is cold.
