The doorsill I saw in Wang's courtyard. Is there a great god to see what case this is carved?

Hello, there are auspicious animals, auspicious clouds, bound branches, gold ingots, animal feet and so on carved on this pier stone.

The second is to form an overall decorative effect with the whole facade, enhance the aesthetic feeling, and have decorative functions such as blessing, auspiciousness and evil spirits. Third, it is a symbol of the level of feudal ritual architecture, a style, a deep structural culture rooted in life and a reflection of life culture. "Obviously, judging from these three photos, it failed to play a practical role, and more reflected the latter two roles!
