"Life is a hero, and death is a ghost." It means to be a hero among people when you are alive and a hero among ghosts when you die. 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. In the last two sentences, the poet satirizes the shameless behavior of those in power in the Southern Song Dynasty by praising Xiang Yu's tragic behavior. There are only 20 short words in the whole poem, but three allusions are used in succession, which can be described as meticulous words and full of sense of justice between the lines.

Li Qingzhao (1March 084 13—— about 1 155), a native of Jinan (now Zhangqiu District, Jinan, Shandong Province) in the Northern Song Dynasty, was a poetess in the Song Dynasty and a representative of graceful and restrained ci school. Li Qingzhao occupies an important position in the history of China literature. After Li Yu, Liu Yong and Qin Guan, she pushed the level of graceful and restrained words to another peak, and was praised as "the first talented woman through the ages".
