Ode to Goose is a five-character ancient poem written by Luo Qi, a poet in the early Tang Dynasty.

Full text: Goose Goose, Quxiang Xiang Tiange. White feathers, floating in green water; The red soles of the feet stir the clear water.

Translation: "Goose! Goose! Goose! " Facing the blue sky, a flock of geese are singing with their necks bent. Snow-white feathers float on the green water, and the red soles of the feet paddle clear waves, just like rowing.

Extended data:

The little poet used a set of antithetical sentences to describe the wild geese swimming in the water from the color aspect. The goose's hair is white, but the river is green. The contrast between "white" and "green" is bright and dazzling, which is the right sentence.

Similarly, the webbed goose is red, the water wave is blue, and "red" and "green" are all gorgeous, so it is. In the two sentences, "white" and "red" are relative, "green" and "green" are relative, and they are a pair of ups and downs. It's wonderful to go back and forth like this and do the opposite.
