Many prehistoric cultural relics have been unearthed in Sanxingdui, Guanghan City, Sichuan Province. According to the study of these cultural relics and house sites, it has a history of 5000 years. Of course, as mentioned above, buildings only leave ruins. Therefore, the study of the artistry of these buildings can only be inferred indirectly from other cultural relics. From some unearthed pottery, we can know that people can already exaggerate their shapes by artistic means, such as "a portrait of a face in the vertical direction", in which the eyes protrude a few centimeters, the mouth stretches horizontally to smile, the nose is curled, and the ears are big and high. Although exaggerated, they are all artistic sculptures in terms of scale and detail. Some people analyze that this is something on the totem pole, which is obviously religious, and it can also be said that it is a combination of prehistoric religion and art.
