Jheng Jhengyin was Jheng Rupei's penname. Coming from Tianjin, he had learned some kung fu and was familiar with the gang's rules. When he was young, he once worked as a teacher in an old style private school, sihshu. Because of financial difficulties he began writing wusia novels. Collectively he wrote 88 books, which chiefly were medium-length novels. Apart from his most famous work, Yingjhua Wang, his other well-known stories include Tiannan Yisou, Lihun Zihmu Cyuan, Hei Fonghuang, Nyu Tuhu and Huitou Ya.

      Yingjhua Wang and its sequel altogether are more than two million words in 103 chapters. They were published as series in a newspaper called 369 Huabao in Tianjin in 1941. The theme of this story is about the revenge of the Huaiyang Bang gang, led by Wang Daolong, on its irreconcilable enemy the Fongwei Bang gang. So Wang led a group of martial arts masters to fight the Fongwei Bang gang on the Yandangshan Mountains. The main story line is simple and clear; the development is suspenseful and sentimental.
