Final answer:
The historical rejection of other cultures as inferior by the Chinese illustrates the concept of ethnocentrism.
Step-by-step explanation:
The historical rejection of other cultures as inferior by the Chinese illustrates the concept of ethnocentrism, which is the belief in the superiority of one's own culture or ethnic group.
China's rejection of other cultures as inferior can be seen in their interactions with foreign nations, such as the refusal to grant equal status to representatives from Western countries.
This attitude can also be attributed to a sense of cultural pride and the belief that China already had everything it needed, as mentioned by Qianlong when refusing Britain's request to establish a permanent embassy in China.
