Hello, everyone. I’m Li Zhi. It’s nice to speak I think it's a pleasure to help others. For example, when you have a good friend in learning problems, you help her, not only will help her solve the problem, but also improve the friendship between you. When you cross the road actively helped an old woman, you will feel that helping others is very simple.When a doctor helps the patient to cure the disease, he will feel happy. In fact, to help others is very simple, it does not have to be a big thing, just around the little things will make the world more exciting!about help here.Thank you for your listening.
