The title of this book adopts the system of knighthood after Cao Wei, and does not use the twenty-class duke since the Qin and Han dynasties, and implements the fifth-class system of dukes and uncles

The knighthood system is nine grades: king, duke, marquis, uncle, son, male, county marquis, township marquis, and guannei marquis.

The king is exclusive to the royal family; There are five clans and meritorious heroes such as duke, marquis, uncle, son, and male, and they all have fiefdoms;

The county marquis, the township marquis, and the marquis of Guannei were knighted for the heroes and their children, and there was no feudal country, and the food and rent tax. Wang Zhinan regarded the official as a product, the county Hou regarded the third product, the township Hou regarded the fourth product, the Pavilion Hou regarded the fifth product, and the Guannei Hou regarded the sixth product.
