Lo Kuan-chung   Luo Guanzhong, Wade-Giles romanization Lo Kuan-chung, original name Luo Ben, also called Luo Guan and Luo Daobun, courtesy name (zi) Guanzhong (b. c. 1330, Taiyuan?, Shanxi province, China—d. c. 1400, Hangzhou?, Zhejiang province), Chinese writer who traditionally has been credited as the author of the classic Chinese novels Sanguozhi yanyi (Three Kingdoms) and Shuihuzhuan (Water Margin, or All Men Are Brothers). Almost nothing is known about the life of Luo. His authorship of Sanguozhi yanyi and Shuihuzhuan (the latter possibly written jointly with Shi Naian), however, is now largely disputed. The first work is a historical narrative, while the second is a semi-historical picaresque novel about a band of outlaws, written in the colloquial style. Both works enjoy continued popularity among Chinese readers.
