Summer quatrain is a five-character quatrain created by Li Qingzhao, a poet in the Song Dynasty, which satirizes the present and expresses grief and indignation.
In A.D. 1 127 (the second year of Jingkang), Jin Bing invaded the Central Plains, and Li Qingzhao's husband Zhao Mingcheng became the magistrate of Jiankang. After the rebellion broke out in the city, Zhao Mingcheng was not thinking about counterinsurgency, but chickened out. Li Qingzhao is ashamed of her country and her husband. When she passed the Wujiang River, she felt the solemn and stirring of Xiang Yu and wrote this poem. The first two sentences of the poem are surprising and straightforward, suggesting that people "live like outstanding people" and make contributions to the country; "Death" should also be a "ghost hero" to become a hero.
