Sparrows are a very small bird that usually lives in cities and villages. They have short mouths, small bodies, and dim feathers. They are easy to become pets in urban and rural environments. Sparrows played an important role in Chinese traditional culture. In the Book of Songs, there was a poem called "Little Ya·Chesha" that described the scene of sparrows jumping on the branches as a symbol of joy and harmony. Sparrows were also often used as an image in poetry. For example, in the poem "Climbing the Stork Tower" by the Tang Dynasty poet Wang Zhihuan, there was a line: "The sun is against the mountains, the Yellow River flows into the sea." The sparrow represented those who desired to pursue a higher goal. Although sparrows were common birds, they also had an important status and symbolic significance in Chinese traditional culture.
