The Hall of Praying for the New Year is one of the most representative buildings in Tiantan Park. Built in the 18th year of Yongle in the Ming Dynasty (1420), it was formerly known as Dasi Hall, which was used to jointly worship heaven and earth. In the 24th year of Jiajing (1545), it was changed into a three-eaves round hall. The top of the hall is covered with clear, medium yellow and green stained glass, which symbolizes heaven, earth and everything, and is also called the tycoon hall. In the 16th year of Qing Qianlong, the three-color tile was changed into a unified blue tile with a golden roof, and it was 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).

The internal structure of the Hall of Prayer for the New Year is unique: the roof is supported by nanmu columns and purlins instead of girders and long purlins. The four "Longjing Columns" inside symbolize the four seasons of spring, summer, autumn and winter. The middle column 12 symbolizes 12 months, the outer column 12 symbolizes 12 hours, and the inner and outer columns represent 24 solar terms. The total number of * * * 28 on the third floor symbolizes 28 stars in the sky. Together with the eight copper pillars at the top of the pillars, there are 36 * * *, symbolizing the 36 highest days.

Tiantan Park is in the south of Beijing, to the east of Yongdingmennei Street in Dongcheng District. Covers an area of about 2.73 million square meters. The Temple of Heaven was founded in the 18th year of Yongle in Ming Dynasty (1420), and was rebuilt and rebuilt during the reign of Qing Qianlong and Guangxu. Now it is a world cultural heritage, a national key cultural relic protection unit, a national AAAAA-level tourist attraction and a national civilized scenic tourist area demonstration site.
