Sometime during the reign of the Shunzhi Emperor, an artist from Suzhou called Wu Ruixian (Chinese: 吳蕊仙) sought refuge with Mao.
The two women collaborated on many compositions, earning renown as 'the two artists of the Mao family' (Chinese: 冒氏兩畫史).
[1] The Guochao Hua Zheng Xulü (Chinese: 国朝画徵续录) described Cai as, 'particularly good at painting landscapes, flowers, animals, and birds,' and, 'adept at imitations.
'[3] She painted many pieces together with her fellow concubine Jin Yue 金鈅, including Auspicious noon, now held in the Nanjing Museum.
[1] In 2001, one of Cai's works painted in 1680, titled Shuihui yuan tu (Chinese: 水繪園圖), appeared at an auction house in Shanghai, where it was sold for 40,000 RMB[4] to an unknown buyer.
