Shi Nai'an (Chinese: 施耐庵; pinyin: Shī Nài'ān, c. 1296–1372) was a Chinese writer from the Yuan and early Ming periods. Shuihu zhuan (Water Margin), one of the Four Great Classical Novels of Chinese literature, is traditionally attributed to him. There are few reliable sources for his biography, much less his literary activity. Source: Wikipedia (en)
