Crescent School advocates the three beauties of poetry creation, namely, the beauty of music, architecture and painting. Therefore, Rainy Lane is a three-beauty proposition of Crescent School.
The so-called beauty of painting refers to the choice and use of characters that appeal to visual images, which can fully reflect the characteristics of China hieroglyphics and have a sense of color. The so-called musical beauty means that the syllables of poetry are catchy and well-arranged, with the beauty of syllables and melodies appealing to auditory images. The beauty of architecture also belongs to visual image, which mainly refers to the physical structure of poetry, the strong adjustment of symmetry and the uniformity of sentences, resulting in regular uniformity or unevenness.
