1. Monument, which is interpreted as "vertical stone" in Xu Shen's Shuo Wen Jie Zi in the Eastern Han Dynasty, is a stone standing on the ground.
At that time, the monument had three main functions. First, it is set in the palace to watch the sun shadow, identify the direction and measure the time. The second is to put it in the temple and tie it to sacrifice animals; The third is to stand on the edge of the tomb, introduce the coffin into the tomb for the funeral and use pulleys. At first, there were no words on the tablet, but later words were engraved, which were called "tablet" and "inscription" in calligraphy art.
The monument we are talking about today has a broad sense and a narrow sense. Broadly speaking, it refers to stone carvings engraved with characters such as Germany, Gong Ming and Chronicle. Such as stone tablets, cliffs, statues, pagodas, inscriptions, boundary markers, epitaphs and so on. In a narrow sense, a monument refers to a rectangular stone with words carved in front of memorial places, buildings or tombs after the Eastern Han Dynasty.
When we study calligraphy, most of the monuments we understand are the broad understanding of the former, that is, the general name of all stone carvings engraved with words (except engraved posts).
Second, the post, Xu Shen's Shuo Wen Jie Zi is interpreted as a "silk book".
The ancients called the words written on bamboo and wood chips bamboo slips. After the late Qing Dynasty, photography technology was introduced to China. Once the calligraphy words were photocopied and bound, they were called posts.
