The Tangzi 唐子 "Master Tang" is a Daoist treatise compiled by the Wu period 吳 (222-280) writer Tang Pang 唐滂 (252－?). The originally 10 juan "scrolls" long book is only preserved in fragments collected by the Qing period 清 (1644-1911) scholar Ma Guohan 馬國翰 (Yuhan shanfang jiyi shu 玉函山房輯佚書). Quotations of the Tangzi were preserved in the collection Yilin 意林 and encyclopedias like Beitang shuchao 北堂書鈔, Yiwen leiju 藝文類聚 or Taiping yulan 太平御覽. The content of the fragements points at leaving the secular world in order to become an immortal.|
