In Chinese culture, the tiger is the king of the beasts.
According to legend, the tiger's tail would turn white when it reached the age of 500 years.
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..
And he appears today. Live long.
