What do you mean by grave, tomb, burial and mausoleum? What is the difference?
The traditional society in China has a strict hierarchical system, that is, the "ceremony" of respect and inferiority, and the strict distinction cannot be confused, and so do the names of daily residence and burial place after death. This is the difference between a palace, a mansion, a house, a home and a mausoleum, a tomb, a grave and a forest.
The "tomb" refers to the underground part, that is, "the tomb is above the ground, and the underground part is the tomb". Together with the above-ground part, it is called "tomb" or "grave". In ancient times, before Qin and Han Dynasties, there was a "tomb instead of a grave", so the "tomb" was generally flat and not higher than the ground, while the "grave" was a mound piled up on the tomb as a mark.
after the death of the emperor, it is well known that it is called "Mausoleum", such as the Mausoleum of the First Qin Emperor, the Mausoleum of the Yellow Emperor, the Ming Tombs, etc. However, people in special periods are also called "Mausoleum" because their status, contribution or fame are almost equal to that of the emperor. For example, the tomb of Dr. Sun Yat-sen in Nanjing is called Sun Yat-sen Mausoleum, and the Guanling where Guan Yu's body is buried in Dangyang, Hubei Province. There is no problem in using "tomb" for princes and princes. The original meaning of "tomb" is high grave, and Cao Cao's tomb is considered to be within the "seventy-two suspected tombs".
