Hua Biao, also known as Optimus Prime, was called Huan Biao in Han Dynasty, which was used as a symbol or memorial building in ancient China. It existed as early as Yao and Shun Dynasties. It is said that Yao was established in the era of Emperor Yao to solicit public opinions. In ancient books, there is a saying that "Yao set up a slanderous wood, and today's Chinese table wood is also", that is, a crossbar was placed on a wooden post and placed on the main road, which means that the people can write their opinions on the slanderous wood, reflecting the sincerity of the king coachable. In the Han Dynasty, most Chinese watches were made of wood, with white cranes standing on the top. In the Ming Dynasty, stone columns gradually replaced wooden columns.
Chinese watches are generally composed of a column foundation, a column body and a column top. In the future, the column foundation will generally be a lotus column base. The column body is mainly round, and there are also octagonal and square shapes, etc. The column body is generally carved with patterns such as dragons and grass rolls; There is a cloud plate on the top of the column, which is called the dew-bearing plate. There is a monster sitting in the plate, which is called "Cheng".
