The whole poem: flowers are full of branches by the stream, birds are singing and flowers are fragrant. There are egrets under the sun, the sun is oblique and the rock is oblique.
A mirror in "weeping willows regard the stream as a dressing mirror" is enough to see the purity and smoothness of the stream, which is like a quiet and beautiful man.
"The mountain stream is as quiet as a jade belt" is even more interesting. The weeping willows are dressing up, the weeping willows are crisp, a mirror-like stream, and the green of weeping willows is reflected in the stream, making the whole stream green like a jade belt.
The most interesting thing is the red dragonfly on the fishing rod. Happy people who love weeping willows, warm currents, green hills and beauty make this dragonfly linger and be deeply attracted by such a sight. So this dragonfly also wants to be a quiet and beautiful dragonfly and enjoy the beautiful scenery around it quietly. A "red" character sets off the "green" jade belt, which is really just the right embellishment.
