Gu Hengbo

Gu Mei (; 1619–1664), better known by her art name Gu Hengbo (), also known as Xu Mei and Xu Zhizhu after her marriage, was a Chinese courtesan, poet and painter. She received the title "Lady (furen)" from the early Qing court, and often addressed as "Lady Hengbo" in Qing writings.
Gu was famous for her beauty and talent within painting and poetry and counted among the elite of courtesans alongside Dong Xiaowan, Bian Yujing and Liu Rushi. She was admired for her paintings of orchids, and published a collection of poems which was given good critics, although few of her works have survived.
Life.
Gu Mei was born near Nanjing in 1619. At the beginning of the Chongzhen reign, Gu Mei became a courtesan in the Qinhuai River district of Nanjing. In her Tower Meilou in Qinhuai district in Nanjing, she hosted a famous literary salon, which counted Chen Liang, Qian Lucan and Mao Xiang among its guests. Yu Huai described Meilou (literally "house of bewitchment") as lavish and extravagant. 
She fell in love with one of her patrons, Liu Fang, promised to marry him and to end her career as a courtesan. When she later changed her mind, Liu Fang committed suicide. 
One of her patrons, the career official Gong Dingzi, paid 1,000 ounces of silver for her services. In 1643, she left her profession to become a concubine to Gong Dingzi and settled with him in the capital. His openly demonstrated love for her attracted much attention during their time, as it offended the norms of Confucian ideals, and her influence over him became legendary. She is known to have saved the Yan Ermei from execution, and to have been the benefactor of the artist Zhu Yizun. 
In 1659 Gu Mei gave birth to a daughter. Anxious to have a son, Gong Dingzi built a private Buddhist temple where the couple could pray for a son.
She was one of the Eight Beauties of Qinhuai described by late Qing officials. The other famed courtesans of this group are Ma Xianglan, Bian Yujing, Li Xiangjun, Dong Xiaowan, Liu Rushi, Kou Baimen, and Chen Yuanyuan.
