Many "Zhuangzi" fragments dating from the early Tang dynasty were discovered among the Dunhuang manuscripts in the early 20th century by the expeditions of Hungarian-British explorer Aurel Stein and French Sinologist Paul Pelliot. They collectively form about twelve chapters of Guo Xiang's version of the "Zhuangzi", and are preserved mostly at the British Library and the Bibliothèque nationale de France.
