Wang Jiu-si (1468～1551) was a literary figure of the Ming Dynasty. His courtesy name was Jingfu, and his pseudonym was Meipi. He was from Huxian, Shaanxi (now Huxian). He became a Jinshi in the ninth year of the Hongzhi era (1496). He was selected as a Shujishi and later appointed as a Jian Tao. During this period, Li Mengyang, He Jingming, and Kang Hai among others came to Beijing one after another, gathering to discuss and advocate that prose must follow the Qin and Han styles and poetry must follow the High Tang style, historically known as the "Former Seven Masters". In the fourth year of the Zhengde era (1509), he was transferred to the Ministry of Personnel as the Director of the Bureau of Appointments, and within the year, he was promoted from Vice Director to Director. In the autumn of the same year, he was demoted to the position of Tongzhi of Shouzhou on charges of being a follower of Liu Jin. The following year, he was ordered to leave his post for the same reason. He once co-annotated the Nan Jing, and to this day, his "Wang Hanlin's Collected Annotations on Huangdi Bashiyi Nan Jing in Five Volumes" is still in circulation. His poetic works include "Meipi Collection", "Meipi Sequel", the song collection "Bishan Yuefu", "Nanqu Ciyun", and the play "Du Fu's Spring" among others.
