First, Confucius traveled around the world. Confucius used his own theory to make Lu develop greatly and gradually become rich and strong. So he wanted to bring development to more countries, so he took his students to study in vassal countries. When Confucius arrived in Chu, the king of Chu heard of Confucius' behavior and quickly ordered someone to introduce him. Worried that Confucius would be reused by Chu, Chen's people arranged for Confucius and his disciples to be surrounded. In this way, Confucius was surrounded for 7 days and all the food he brought was eaten up. Finally, Zi Gong found Chu and asked Chu to send troops to meet Confucius.
Second, Confucius teaches and educates people. At the age of 30, Confucius began to set up private schools to educate students. His educational proposition is that no matter what social class you are in, you can become his students as long as you want to study, breaking the government's system that the poor can't study. So Confucius was widely respected at that time. Confucius has two purposes in educating students. The first is to cultivate students' moral character and the second is to cultivate students' political ability. Therefore, many Confucius students become officials, which is of great significance for promoting the development of Confucianism.
Third, the historical contribution of Confucius. Confucius' thoughts still influenced generations in China. It is an excellent part of China traditional culture and a cultural tradition that must be inherited and developed. Confucius thought is the mainstream thought in China's feudal society for more than 5,000 years, and it is precisely because of the existence of Confucius thought that the Chinese nation can continue and have today's splendid and prosperous civilization.
