What do you mean, the tortoise is a fur shell, the musk deer is a rabbit, the eagle's eye is wearing a fur hat, and the thrush's mouth is smart, and it is locked in a cage?

This is an old story, because there is no distinction between "three tones" and "four tones", and it also reflects the knowledge level of old artists and the mistakes in traditional culture.

Turtles are psychic orifices: Turtles' shells can be psychic orifices (so turtles are killed).

Cuiwei: Jade birds can be used as flags (so jade birds are killed);

Fragrant roe is a kind of musk: Fragrant roe has musk (musk generally refers to all animals that produce spices), (so fragrant roe is also killed).

Rabbit hair: the hair on the rabbit's tail can be used as a fine brush (called rabbit hair), (so the rabbit was also killed)

The eagle wears a fur hat for its sharp eyes: because of its sharp eyes, the eagle can hunt (so it is kept in captivity), and wear a fur cover when it is no longer hunting (otherwise the eagle will peck people's eyes);

Thrushcross's clever mouth is locked in a cage: Thrushcross is good at imitating all kinds of sounds because of his clever mouth, which is like being in prison.
