Take my brother out to see the almanac.

The yellow calendar, or imperial calendar, is based on the lunar calendar in China, and many calendars indicate the good or bad luck of a day.

According to legend, Huangli was created by Emperor Xuanyuan, so it is called Huangli, and it is also commonly known as "Shu Tong" among the people. However, because the word "book" in Tongshu is homophonic with the word "lose", it is also called "Tong Sheng" because it is taboo.

The main contents of the yellow calendar are the schedule of the 24 solar terms, good luck and bad luck every day, and the luck of the Chinese zodiac. In the Qing Dynasty, the almanac was compiled by Qin Tianjian of the imperial court.
