Liu (16 18 ~ 1664), whose real name is Yang Ai, also known as Hedong Jun, named himself this way because he read Xin Qiji's "He Xinlang thinks I'm weak" in the Song Dynasty, "I see how beautiful the green hills are, but I expect the green hills to see me like this". Jiaxing, Zhejiang, a poetess in the late Ming and early Qing Dynasties, was also a famous talented singer, who was good at poetry and painting.
Liu was clever and studious since childhood, but because of his poor family, he was robbed and sold to Wujiang as a maid in his early years. When I was young, I fell into Zhangtai, changed my name to Liu Yin, and went to Jiangsu, Zhejiang and Jinling in troubled times. Other works mainly include Grass on the Lake, Wuyinsao, Letters, etc. Liu's calligraphy won the admiration of later generations, and he was called "iron fist and silver hook, which once collected wonderful traces".
