What is the name of the neutron column next to Tiananmen Square?
According to legend, Yao Shi set up wooden signs on main roads for people to write suggestions and criticize the shortcomings of the times. The ancient watches in China were all made of wood. During the Eastern Han Dynasty, stone pillars were used as China's watches. The function of China's watch disappeared and became a big pillar erected in front of palaces, bridges and graves. Chinese watches are usually carved from white marble. The base of a Chinese watch is usually square, and it is a lotus or sumeru constellation, with dragon patterns carved on it. On the dragon column, the column is carved with dragon cards and decorated with moire patterns. A cloud board is inserted horizontally at the upper end, which is called slander wood; There is a exposed disk at the top of the stone pillar, which is circular, so it corresponds to the circular place. The beast squatting on it is the legendary beast roaring towards the sky, or looking up to the sky.
