This unique culture has a long history and has a far-reaching and extensive influence among the people. China people did not deliberately protect its existence, but naturally passed it down.

Since ancient times, there have been hundred schools of thought such as Buddhism, Confucianism and Taoism in choosing auspicious days, and books such as Jade Sagger, Wanbaolou, Aotou Shu Tong, Lingqi Classic and Xie Ji Frontier Defense have been handed down, and there are many ways to choose auspicious days.

At present, the most detailed and representative document about auspicious choice is Xie Ji bian Fang, which was compiled in Qianlong period of Qing Dynasty.

Third, the traditional calendar

Marking the year, month, day and time with heavenly stems and earthly branches is a unique method in China, and the Gregorian calendar is a traditional calendar marking the year, month and day with heavenly stems and earthly branches. Gregorian calendar is a perpetual calendar based on the China lunar calendar. Legend has it that it was created by Xuanyuan Huangdi, so it is called solar calendar.

It is also commonly known as "general book" among the people, but it is also called "tong sheng" because the word "book" in the general book is homophonic with the word "lose". The main contents of the Gregorian calendar are 24 solar terms, such as daily taboos, dry branches, spiritual values, stars, moon phases, zodiac luck, auspicious and evil spirits (ecliptic, underworld) and so on.

"ecliptic" is a special term in astronomy. There are ecliptic and equator in astronomy, but there is no "underworld". The concept of "evil day in the underworld" is a term coined by the ancient yellow calendar compilers relative to "auspicious day in the zodiac".
