Make friends with each other and water the roots of trees. What's the meaning

“When communicating with people, you need to be sincere, and when you water a tree, you need to water its roots.” This means that when you interact with people, you need to be sincere and treat each other with sincerity, just like when you water a tree, you need to water its roots.

When you water a tree, if you don’t water it at the roots, it means you haven’t watered it at all. How can you make real friends if you don't make friends with others? Every step from acquaintance, knowing each other to falling in love is wonderful. If you want to understand someone, you must treat the other person sincerely and gain the other person's recognition. Only by giving first can you fully understand others.

This sentence comes from the work "Sunny Sky" by the famous Chinese writer Haoran. The original text is: "To make friends with people and to water the roots of trees, people have to be conscientious and appreciate praise.
