Bai Hu (白虎) is the White Tiger, one of the Four Symbols of the Chinese constellations.
In Chinese culture, the tiger is the king of the beasts and has been presented with a 王 on his forehead for centuries. According to legend, the tiger's tail would turn white when it reached the age of 500 years. In this way, the white tiger became a kind of mythological creature. It was said that the white tiger would only appear when the emperor ruled with absolute virtue, or if there was peace throughout the world. It is known as Bai Hu in Chinese, Baek-ho in Korean, Byakko in Japanese and Bạch Hổ in Vietnamese. It represents the west and the autumn season.
