Summer quatrains is a five-character quatrain written by Li Qingzhao, a poet in the Song Dynasty. This is an ancient poem that satirizes the present and expresses grief and indignation. The first two sentences of the poem are surprising and straightforward, suggesting that people "live as outstanding people", make contributions to the country and serve the court; "Death" should also be a "ghost hero" to be a hero with indomitable spirit. Deep patriotism gushed out and shocked people.
