Different people have different views on the value of life. Some people believe that living will make other people's lives better and happier, and that the value of life lies in contribution. Some people believe that "If a person does not serve himself, he will be punished by heaven and earth." He lives in this world just to eat, drink and have fun, so that his life is not in vain. Zhang Side is a person with the same idea as before. He serves the people wholeheartedly and does good deeds one after another. One by one. Maybe some people think that these are "ordinary" trivial things, why bother? However, some people often fail to do even these small things. In fact, it is a small thing that can reveal whether a person's inner world is good or bad, beautiful or ugly.
