Then correct answer is: China influenced Japan, Korea, and Burma in this areas:
The influence China had on these three countries reached a wide range of their social lives, such as political organization, social activities, intellectual development.
In the case of Japan, China wanted to take control of the nation, but Japan resisted. China tried hard but Japan opposed gradually until it limited the influence in order to reestablish the traditional Japanese culture. Chinese influence in this period can be seen in architecture such as pavilions that blend in with nature, and in art, with monochrome paintings. And the Japanese writing was influenced by the Chinese characters.
In the case of Korea, although the presence of China was short, it really impacted Korea in the long term, like the religious influence of Buddhism or the bureaucracy government style of China.
In the case of Bruma, the Chinese presence lasted longer. The cultural influences were in the school system, writing, Confucionist ideas, agriculture, politics and in the military organization.
