Because they think they play an important role in their children's growth, they hope to help them better understand the world and meet the challenges in life in this way. Preaching is a traditional way of family education, which emphasizes the role of parents as authoritative figures and guides children's growth by telling the truth, demonstrating behavior and providing guidance. Although preaching can sometimes play a role, excessive or improper use will bring negative effects. For example, regular preaching may make children feel bored, disgusted and even rebellious. In addition, preaching may not necessarily touch the inner problems of children, and it is difficult to really solve them. In contrast, modern parents pay more attention to establishing good communication and interaction with their children, respect their individuality and needs, and adopt a more flexible and open way to guide their children's growth. They will discuss problems with their children, listen to their thoughts and opinions, and try to find the best solution to the problems. This more inclusive and open way is called "democratic" education, which can promote children's all-round development and growth.
