Introduction to the Xiangbi Stone Sheep: Entering the prologue hall, the first thing that catches the eye is this bronze screen wall. The screen wall is inlaid with the word "Xiang", which is the name of Huaibei in ancient history. In front of the screen wall is a stone sheep. It is a work of the Han Dynasty and a national first-class cultural relic. The original is displayed in the Provincial Museum and this is a copy.
