Yan Zhitui (Chinese: 顏之推; pinyin: Yán Zhītuī; Wade–Giles: Yen Chih-t'ui, 531–591) courtesy name Jie (Chinese: 介) was a Chinese calligrapher, painter, musician, writer, philosopher and politician who served four different Chinese states during the late Southern and Northern Dynasties: the Liang Dynasty in southern China, the Northern Qi and Northern Zhou Dynasties of northern China, and their successor state that reunified China, the Sui Dynasty. Yan Zhitui was a supporter of Buddhism in China despite criticism by many of his Confucian-taught peers. Yan was also the first person in history to mention the use of toilet paper.
