Stone reliefs in the tombs of the Han Dynasty and some silk paintings handed down after the Han Dynasty are often intertwined with anticlimactic images. This kind of figure did not exist before the Han dynasty, that is to say, it was invented and created by the Han people.

Nowadays, it is generally believed in academic circles that these two coitus figures are Fuxi and Nu Wa. Qing Dynasty scholars Feng and Feng Yunzhu also thought so in their book Stone Lock Stone Lock, which is based on what Wang Yanshou, a poet in the Eastern Han Dynasty, said in Luling Photoelectricity Fu: "The five dragons have two wings and nine heads. Fuxi scales, Nu Wa snake body. The wilderness is simple and looks awkward. "

The portrait of Luling Guangdian contains the images of ancient emperors, such as Wulong, Ren Huang, Fuxi and Nuwa. Shan Li quoted Liezi as saying that "Fuxi Nuwa has a snake face and the virtue of being a great sage", which is from Liezi Huangdi (Liezi was written by Zhang Zhan in Jin Dynasty).

Wang Yanshou did not say whether Fuxi and Nu Wa were having intercourse. However, on the list of reliefs in some Han paintings, it is clearly indicated that the characters who are anticlimactic are Fuxi and Nuwa. Some people think that this means that Fuxi and Nuwa are husband and wife, and the mating between husband and wife means that men and women make peace and give birth to all things in mankind. Indeed, in some portraits, Fuxi and Nu Wa are still painted with villains, which probably means strangers. But if you look at those portraits carefully, you will know that this explanation is not completely accurate.

In the Han Dynasty, there was no saying that Fuxi and Nuwa were husband and wife, but the only thing quoted in The History of Daoism and Houji II in Customs Tong was "Nuwa, Fu", so in the Eastern Han Dynasty, there should be a saying that Fuxi and Nuwa were brother and sister, not husband and wife. The earliest time to say that they were husband and wife was probably written by Li Rong in the Tang Dynasty. He said: "At the beginning of the universe, there were only Fuxi and Nuwa in Kunlun Mountain, and there was no one on earth, so we thought they were husband and wife." From then on, Fuxi and Nuwa were said to be husband and wife, so Fuxi and Nuwa were in the portraits of the Han Dynasty.
