Introduction to bamboo slip sculptures: Bamboo slip sculptures are divided into three groups: left, middle and right. Whether viewed from above or straight up, the entire set of bamboo slip sculptures are arranged in the shape of "pin". When looking straight up, the middle body is the highest, and the two sides gradually lower, forming the shape of the Chinese character "mountain", which symbolizes the military attainments of Sun Tzu, the originator of military strategists, standing high on the mountain.
