What is the main purpose of the Temple of Heaven in Beijing?

New year prayer hall. Built in the 18th year of Yongle in the Ming Dynasty (1420), it was originally a rectangular hall for offering sacrifices to heaven and earth. In the twenty-fourth year of Jiajing (1545), it was changed into a three-dome hall, and the top of the hall was covered with blue, middle yellow and lower green colored glass, which symbolizes heaven, earth and everything.

In the 16th year of Qing Qianlong (175 1), the three-color tile was changed into a unified blue tile jinding, named "Hall of Praying for the Year", which was a special building in the Valley of Praying for the Year in Meng Chun (the first month).

There are 28 Jin Sinan wooden pillars in the hall where people pray for the New Year. The four pillars in the inner circle symbolize the four seasons, the middle circle 12 symbolizes1February, and the outermost circle 12 symbolizes 12 hours and the stars on Sunday.

The wood-burning stove is a huge round brick stove, which is made of green glass. At the beginning of the worship ceremony, a clean calf is first placed on the stove, and pine branches and reeds are burned into firewood to meet the gods, which is called "burning firewood to welcome the emperor". After the ceremony is completed, all the offerings and greetings listed in the case of gods and gods are transported to the furnace for incineration, and the emperor also needs to stand by and watch, which is called "looking at Liao".
