What changes have taken place in the functions of plaques in the Song Dynasty in China?

In the Song Dynasty, as a function of naming buildings, the tablet has not only stopped at naming a name, but also started to weigh the contents of the inscription. It was recorded in the ancient book Liu Yungu at that time that since the Song Dynasty, ordinary people began to give each other plaques as gifts, and some rich people even made plaques out of gold to preserve them for a longer time and achieve the effect of making a name in history.

That is to say, since the Song Dynasty, the function of China tablet has changed, and the texture of the tablet itself has also changed.

In the Song Dynasty, besides exchanging plaques, there were occasions when emperors gave gifts. For example, when Song Huizong was in China, he presented a plaque of "Weihui Temple" to the temple of Chen Yuanguang, a general of the Tang Dynasty, to commemorate his contribution to the development of Zhangzhou and Chaoshan areas.
