Han Yu originally meant that there is no difference between Huayi and Huayi, but Xu Heng abruptly changed it to that there is no difference between Huayi and Huayi. Now it's good. All the traitors regard Xu Heng's words as a wise saying, and even regard this sentence as the theoretical basis for their treason. Many people have devoted themselves to the cause of the traitors, which not only endangers the security of the country, but also affects the whole country. It has influenced Chinese people for dozens of generations, so much so that this sentence can still be seen today.

Han Yu wrote these sentences after reading Confucius's books. His original meaning was: If the princes adopt the etiquette and customs of the Yi Di, then they should be classified as Yi Di; if the princes adopt the etiquette and customs of the Central Plains, then they are Central Plains people; in fact, Han Xin’s sentence seems It makes sense. After all, there are differences between China and foreign countries. If you want to integrate into several groups, you must admit that you are one of them, so as not to disrupt traditional etiquette and customs.

However, Xu Heng, who was unknown in history, deliberately distorted Han Xin's original intention, and even argued that he got his words from Han Yu. Xu Heng completely changed Han Yu's Huayi distinction into Huayi no distinction, which conveyed a wrong concept to future generations and also gave those who did evil things a very weighty excuse; although Xu Heng It's easy to put it lightly, but it has had a heavy impact on Chinese history. It can even be said to have poisoned China for 800 years, and it is very likely that it is still affecting people today.

It should be said that Xu Heng laid the theoretical foundation for treason, because his words gave those who were traitors a theoretical basis, so they could do those bad things with confidence, and even So natural. I can only say that Xu Heng’s words ruined many lives and caused great losses to history.
