This paper expounds the three schools of China's ethical thoughts and their development process.

Confucianism explains Taoism. Confucianism refers to the school founded by Confucius, also known as Confucianism. As the official ideology of China, it has been in the mainstream ideology for a long time, and its influence has spread to the Korean Peninsula, Japan, Indochina Peninsula, Central Asia, Southeast Asia and other regions. Buddhism was founded by Siddhartha Gautama in ancient India (now Nepal). Siddhartha is also called Buddhism because he is Sakyamuni Buddha. Taoism refers to the religion founded by the immortals of Huang in the Eastern Zhou Dynasty according to the Tao Te Ching (Laozi) and the South China Classic (Zhuangzi), which is a local religion in China. It is widely spread in China and has a great influence. Taoism is a native religion in China.

Confucianism, Buddhism and Taoism are China's earliest views on the scope of world culture in ancient times, and the Indian cultural circle represented by Buddhism is the closest and earliest culture to China among many foreign cultures outside the scope of Greater China cultural circle. It is also the earliest culture that let China serve foreign things and foreign things serve Chinese things, which embodies China's open and inclusive mind. With the rapid development of science and technology, the earth is also like a small village, and more excellent cultures are presented to the world. Learn from each other's strong points and make everything harmonious, which is the true spirit of China and the blessing of the world.
