What are the characteristics of the animal sculptures buried in Tang Dynasty tombs compared with those of the Han Dynasty?

The pottery sculptures of domestic animals such as cows and sheep and poultry such as chickens and ducks in Tang Dynasty tombs are far more advanced than those of the Han Dynasty, and the three-color reclining oxen unearthed from Tang tombs in Qin'an, Gansu Province, in 1965 are also relatively rare. Here again cited Hebei Tang tomb unearthed a crouching ceramic cow, the right front foot lifted, head up, as if to stand up in a moment. Its stillness has a dynamic demeanor, reminiscent of the Western Han Huo Zaiwei stone sculpture group of the reclining horse. This instant dynamic, in sculpture modeling is quite difficult to master. It may be that the ancient master craftsmen can penetrate into the life, familiar with the habits of cattle and horses, and thus can sculpture that kind of shape and spirit of the moving image.
