Eight-character motto of sparrow

Idioms: "Silence" and "Birds get together and make noise"-explain the noise of birds.

There are no birds in the door-that means birds can't fly high or far.

As the saying goes, "The magpie is happy, but it cries sadly"-the magpie's cry indicates a happy event. Poetry: "Swallows know the swan's ambition"-it means that the sparrow is not flying high (it can also mean that the sparrow is timid)
