In the mountain there lives a beast that looks like a macaque but with white ears.
Xing Xing can stand on their hind legs and walk like humans.
It is said that though Xing Xing cannot foresee the future, they know everything about the past.
Eating their flesh will allow the consumer to run extremely fast.
NB: The character 狌 can also be pronounced "shēng," so you may also find this beast being referred to as "Sheng Sheng" as there is some debate over which is correct.
