Lanxi Acura is a famous work by Dai Shulun, a poet in the Tang Dynasty. The poem describes the scenery along the coast of Lanxi in spring night and the fishing mentality of fishermen. "The cool moon hangs like a brow on Liuwan, and the more it looks in the mirror", two sentences are about the moon, trees, rivers and mountains reflected in the water under the moonlight. A word "cool" makes people feel that spring is still cold, and a word "mirror" makes people feel the silence of the moonlit night. This poem is beautifully written and exquisite. The phrase "Peach blossoms rain in Lanxi for three days, and carp come to the beach in the middle of the night" gives people a completely different feeling. For example, quoting a phenological phrase circulated by the people is catchy and unpretentious, which describes the fact that there are many fish in Lanxi River after the spring rain. Although the upper and lower couplets are written in different ways, they are also harmoniously combined into a leisure fishing map on the riverside in spring night.
