China's culture is profound, and one square character is enough for a person to study for a lifetime. When studying culture, it is suggested to look at historical nodes, such as China Three Kingdoms period, Tang Dynasty culture and Qing Dynasty culture. The mainstream of world culture is age of steam, Industrial Revolution and Renaissance. These differences lie in that China is a country under the disguise of culture, while the world is a country composed of some ethnic groups. Cultures are different. For example, there are hundreds of dialects in India, and the official language is only English. On the other hand, China has no obstacles in basic communication and writing in Mandarin.
