However, different thinkers and texts convey different opinions on this issue. The prominent Tang Confucian Han Yu, for example, wrote in his essay "Yuan Dao" the following: "When Confucius wrote the "Chunqiu", he said that if the feudal lords use Yi ritual, then they should be called Yi; If they use Chinese rituals, then they should be called Chinese." Han Yu went on to lament in the same essay that the Chinese of his time might all become Yi because the Tang court wanted to put Yi laws above the teachings of the former kings. Therefore, Han Yu's essay shows the possibility that the Chinese can lose their culture and become the uncivilized outsiders, and that the uncivilized outsiders have the potential to become Chinese.
