The almanac is a kind of almanac that can simultaneously display various calendars such as solar calendar, lunar calendar and dry calendar, and has a large number of rules and contents related to seeking good fortune and avoiding evil. In ancient times, the almanac was calculated and published by Qin, so it was also called the almanac. Its content guides the farming opportunities of Han working farmers, so it is also called the farmers' calendar. Han people are commonly known as general books. However, because the word "book" is homophonic with the word "lose", it is also called "Tong Sheng" because of its taboo.
