Biography Liu Rushi (1618-1664)

His original surname was Yang, and his given name was Yinglian. He changed his surname to Liu and his given name was Yin. Later, her name was changed to Shi, also known as Hedongjun, also known as Miwujun. She was a native of Jiaxing, Zhejiang. She was sold to the famous prostitute Xu Fo's family in Shengze when she was young and became an adopted daughter. Educated by Xu, Liu's poems are good at seven-character style, subtitles and step rhymes, and he has Yu Shinan and Zhu Suiliang's calligraphy skills in calligraphy. When he was a little older, he lived in a brothel. It is the first of the eight beauties of Qinhuai. In Songjiang, with her peerless talent and beauty, she interacted with members of the Fushe, Jishe, and Donglin parties. She often wore Confucian men's clothing, talked about current affairs with various literati, and sang poems. In the 14th year of Chongzhen in the Ming Dynasty (1641), Qian Qianyi, the leader of Donglin and Changshu, and Liu Rushu became friends with the Qin and Jin Dynasties. The two lived together in Jiangyun Tower and enjoyed each other's reading and discussing poetry. Qian jokingly called Liu Ru "Liu Rushi". When the Ming Dynasty died, Liu persuaded Qian to die for the festival and choose one of three ways to die: knife, rope, or water. Qian's face looked troubled, so he jumped into the lotus pond and attempted to die. After Qian Qianyi surrendered to the Qing Dynasty, he was expelled back to his hometown due to suspicion and died of depression. The Qian family took the opportunity to demand money from Liu Rushi, who then committed suicide.
