What are the characteristics of sculpture in Song Dynasty in overall modeling?

Generally speaking, in the artistic achievements of ancient Chinese sculpture, the overall shape of the sculpture in the Song Dynasty is relatively loose, which can't be compared with that in the prosperous Tang Dynasty. However, from the perspective of full of life breath, it still has its outstanding points, which is precisely the different characteristics produced by the historical conditions of different societies. When the author visited Song Ling for the first time from Xi 'an, where the Tang Tomb is located, in 1954, he gave me the impression that the image of Song Ling stone carvings was shrinking and lifeless, and the whole statue ranks looked dull and lifeless, unlike the Tang Tomb stone carvings. 1979 came to Songling again in winter, because the arrangement of time and traffic conditions is better, so we can observe and compare it back and forth. It is found that some statues, especially some animals, such as Swiss beasts, Swiss birds, pommel horses and even slow-moving elephants, unexpectedly show vivid and moving images. Because in a statue of a general's mausoleum, no matter whether it is a civil servant, a guest envoy or a royal horse pawn, it is necessary to stand straight, serious and neat, without any free movement, and it is easy to make people feel dull. But for some animals that are not easy to tame, it is difficult for sculptors to restrain them just by standing or standing on the stone platform.
