Introduction to Shi Xiangsheng: The Shi Xiangsheng on the Song Ling Shinto is relatively well preserved, from which we can see the changes in the stone carving style in the early and late Song Dynasty. In the early period, the shapes were simple and the carving techniques were rough; in the middle period, they turned to realism, depicting reality; in the later period, they moved towards liveliness, with more skillful techniques than before, and more delicate depictions of characters and animals.
