"Shui Shu" is an ancient Chinese character of the Shui people, who call it "Le Sui", which means writing, "Sui" means water (home), and "Sui" is a writing or book of the Shui people. Among the 56 ethnic groups in China, 17 ethnic groups have their own traditional Chinese characters, and Shui script is one of them. It is an ancient symbol similar to Oracle Bone Inscriptions and inscriptions on bronze, which records the astronomical, folk-custom, ethics, philosophy, aesthetics, law and other cultural information of ancient Shui people, and is known as the "living fossil" of hieroglyphics. Shuishu is the general name of ancient Shui characters and ancient books, one of the 56 ethnic groups in China. Shui Shu has other honorary titles, such as Book of Changes and Encyclopedia of Aquarium, which is an important book to interpret the long, vicissitudes and bitter history of Aquarium. At the same time, Shuishu is also known as "the precious living fossil in the ancient cultural treasure house of China", and it is the last territory where hieroglyphics have not been developed.

For thousands of years, Shuishu has become a kind of "oppressed and restricted" character because of its mysterious writing structure and special use, and it has been difficult to spread among the people. Judging from today's research results, Shui Shu is usually regarded as a witch book. The manufacturing time of Shuishu is very old. Some scholars speculate that the origin of Shui Shu can be traced back to Zhixia generation, and "Shui Shu has a certain marriage relationship with Oracle Bone Inscriptions, an ancient Yin people". The place where Shuishu was made was first in the northwest, then introduced into Jiangxi from the north, and then moved from Jiangxi to Guizhou Province, "so it was brought with it." The structure of ancient Shuishu characters can be roughly divided into the following three types: first, hieroglyphics, some of which are similar to Oracle Bone Inscriptions and Jinwen; The second is imitation of Chinese characters, that is, reverse writing, reverse writing or changing the writing method of Chinese characters, and the third is religious characters, that is, various password symbols representing the primitive religion of the Shui people.
