How many bricks are there in Beijing Temple of Heaven? There are many sayings that it is 15258 floor tiles, but according to China Cultural and Historical Relics 194 1, "* * * counts as 13579 tiles." I believe the argument of 13579, because in China culture, the odd numbers of one, three, five, seven and nine are yang; Two, four, six and eight are negative numbers. Nine is the largest yang number, which was used by emperors in many ancient occasions (such as "the glory of the Ninth Five-Year Plan"). In the Book of Changes, the sky is Yang and the earth is Yin. Of course, the Temple of Heaven uses Yang numbers. And 13579, that is, the combination of all positive numbers, reached the extreme value of "nine".

Tiantan Park, formerly known as "Heaven and Earth Temple", is located at No.7 Tiantan Dongli, Dongcheng District, Beijing. Built in 1420, 1530 was renamed "Tiantan". It is the place where emperors of Ming and Qing Dynasties "offered sacrifices to heaven" and "prayed for blessings", with a total area of 273 hectares. It is the largest existing ancient sacrificial building complex in China. 1 965438+65438 in 2008+1October1,which has been opened to the outside world. The opening hours are 06:30-2 1:00 (tickets will be closed at 20:00 in the off-season and admission will be at 20:00 at the latest).

The Temple of Heaven has two walls, forming an inner altar and an outer altar. The main buildings are the Hall of New Year Prayer, the Royal Dome and the mound. The dome is built on the north-south longitudinal axis. The altar wall is round in the south and round in the north, which symbolizes the round place. The ball altar is in the south, the valley prayer altar is in the north, and the two altars are on the same north-south axis, separated by a wall. The main buildings of the ball altar are the ball altar and the imperial dome, and the main buildings of the valley prayer altar are the hall of prayer for the new year, the palace and the door of prayer for the new year. The Hall for Praying for the New Year was built in the 18th year of Yongle in the Ming Dynasty (1420), formerly known as the Great Sacrifice Hall, and is a rectangular hall. The Hall of Prayer for the Year is 38.2 meters high and 24.2 meters in diameter, symbolizing the stars of the four seasons, December, twelve o'clock and Sunday respectively. It is the only existing Tang Ming-style ancient architectural complex and the main building of the Temple of Heaven. Waqiu was built in Jiajing nine years in Ming Dynasty. Every winter solstice, a "celestial sacrifice ceremony" is held on the stage, which is the so-called celestial altar. The echo wall is the round wall of the Temple of Heaven. Because the wall is hard and smooth, it is a good reflector of sound waves, and because of the precise circumferential curvature, sound waves can be continuously reflected along the inner surface of the wall and spread forward.
