The sentence "Don't salute Shu Ren, don't execute the doctor" comes from China's classic book "Book of Rites Quli", which means that Shu Ren (ordinary people) should not be discriminated against or ignored in etiquette; In criminal law, doctors (nobles) should not enjoy privileges or be exempted from punishment.

1. First of all, "courtesy is no less than Shu Ren" emphasizes the universality and equality of etiquette. In ancient China society, etiquette was an important means to maintain social order and hierarchy. However, for Shu Ren, they often face many unfair treatments, such as being unable to receive a good education and poor living conditions.

2. So "courtesy is no less than Shu Ren" means that etiquette should not exclude Shu Ren, but should be treated equally. Secondly, "being a doctor without punishment" means that doctors should not enjoy privileges or immunities in criminal law. In ancient China, doctors were nobles or senior officials, and they often had great power and social status.

However, if they commit a crime, they can escape punishment or get a lighter punishment, which is unfair. Therefore, "not being punished as a doctor" means that doctors should be fairly tried and punished, and should not escape guilt because of their noble status. The significance of this sentence lies in emphasizing social justice and equality.

Whether it is etiquette or criminal law, it should be applied to everyone and should not be different because of different status and status. This is also a kind of restriction and supervision of power, reminding people not to enjoy privileges or immunities because of their different status or status.

Rites cannot be less than Shu Ren, and punishment cannot be the source of doctors.

1. The source of the sentence "No doctor can be punished if he is impolite" can be traced back to The Book of Rites, one of the ancient classic documents in China. The Book of Rites is one of the Confucian classics and a compilation of etiquette system, customs and ethics in ancient China. It contains a large number of ancient documents and materials, reflecting the political, cultural and social life of ancient China.

2. In the Book of Rites, "Shu Ren is welcome, and the doctor should not be punished" is used to describe the differences in etiquette between people of different classes in ancient China society. Specifically, this sentence means that the rules of etiquette are not applicable to Shu Ren, that is, Shu Ren is not respected and treated by etiquette.

At the same time, the punishment will not be directed at doctors, that is, doctors will not be punished for crimes. This thought reflects the strict hierarchical concept and power consciousness of ancient China society. In ancient China, the social hierarchy was strict, and people of different classes enjoyed different rights and treatment.

4. Doctors, as nobles or senior officials, are at the top of the social hierarchy, while Shu Ren is at the bottom. This concept of hierarchy was reflected in the political, economic, cultural and other fields in ancient China. At the same time, "courtesy can't be inferior to Shu Ren, and punishment can't be superior to doctors" also embodies the characteristics of ancient legal system in China.
