There are two main cores to measure a good piece of jade, one is the overall appearance of its jade material, the other is its carving, as the saying goes, "Good jade matches good work", "Three parts of materials, seven divisions of labor" and so on; I know there are several schools of jade carving in China, namely, jade carving in shanghai jade carving, Suzhou, Yangzhou, Guangdong in the south and Beijing in the north. Shanghai school pays more attention to jade carving, with rigorous modeling and bold innovation; Soviet workers are meticulous, material-saving and vivid; Yangzhou workers generally conceive first and then carve; The style of northern workers pays more attention to heroism!

China jade carving culture is profound and has a long history, and I have only a little knowledge. If I say something wrong, I hope you can all be friends!
