"Dunhuang before Dunhuang" —— What are the four beasts in the picture of the four gods and clouds?

In "Four Gods Clouds and Gas Map", four kinds of beasts, Qinglong, Baihu, Suzaku and Xuanwu, roam the sky together and are at ease. In the picture, the dragon and the white tiger are majestic, but the dragon opens its mouth and claws, and its eyes are wide open. The white tiger looks solemn and imposing. Suzaku is called the celestial beast, and Xuanwu is the god of the north. Suzaku and Xuanwu floating clouds in the picture are smart and full of elegance. The four animals in the painting have rich colors and smooth lines, which have obvious characteristics of Western Han painting. The Four Gods Clouds and Gas Map is more than 600 years earlier than Dunhuang frescoes, and it is the oldest and best preserved frescoes seen in China. The four gods are now in the Henan Museum.
