There is no doubt that Japan, South Korea and North Korea in East Asia are deeply influenced by Confucian culture in China. These three countries first learn from China in writing, which is an important carrier of culture. From this aspect alone, the three East Asian countries can't get rid of the influence of Confucian culture in China. In addition, from the external point of view, taking Japan as an example, the Japanese sent a large number of envoys to China from the Tang Dynasty in China, bringing back to Japan a large number of brilliant flowers of human civilization such as institutional classics, advanced production technology, literature and art, music, painting, religion and philosophy, and even including national laws, the establishment of government agencies, costumes, daily life and folk festivals based on the Tang Dynasty in China. Japanese traditional culture is still a living fossil for studying ancient China. Of course, it is undeniable that the Japanese, on the basis of absorbing China's ancient civilization, combined with their own national advantages, further developed the Confucian culture originating from the East, and branded it as unique to the Japanese nation. Therefore, Japanese Yamato culture is closely related to Confucian culture in China.

As for North Korea and South Korea, as vassals of China for a long time in history and bordering on China, their politics, economy and culture are deeply influenced by the Confucian culture in China.

Geographically, Southeast Asia is located at the intersection of China and India, two ancient civilizations of mankind, and is greatly influenced by the two countries in culture, so this area is also called zhina, India. Generally speaking, in Southeast Asia, except for Viet Nam, which is greatly influenced by China and shows obvious China characteristics, other countries and regions are obviously influenced by India.
