Zheng Changshi (1769—?) ), the character Pingjie, later renamed Chonghui, a native of QinghaiYang County, is now a native of Fengtang Town, Chao'an. Young and intelligent, never forget to read. Zhongxiucai, later Ming Jing (Gongsheng), never became an official in his lifetime. He has been engaged in teaching more time, and has successively applied for apprenticeships in Chaoyang, Nan'ao, Jieyang and other places. He participated in the reconstruction of Hansan Academy in Fucheng and was one of the directors of the reconstruction project. Good at poetry, erudite and versatile. He is proficient in the literature of the township and state, has a wide range of natural knowledge, the study of special objects, and has the talent of economics (through the world to help the people). Huang Antao, the prefect of Chaozhou, once asked about the dredging of the Han River waterway, that is, he drew a detailed map and put forward opinions on the evacuation, which was very appreciated and hired to preside over the East Corner Yoshijuku. Inspector Qi Shigong of Guangdong inspected Chaozhou, and Chang Shi submitted the "Ten Thousand Words and Strategies for Current Affairs", which was believed to be not only a man of poetry and literature, but also a scholar of the scriptures, so he was hired to serve as a consultant in the shogunate. There are many biographical works, and there are many subjects, but I have not seen many of them today.
