The oldest surviving "Zuo Zhuan" manuscripts are six fragments that were discovered among the Dunhuang manuscripts in the early 20th century by the French Sinologist Paul Pelliot and are now held at the Bibliothèque Nationale de France. Four of the fragments date to the Six Dynasties period (3rd to 6th centuries), while the other two date to the early Tang dynasty (7th century). The oldest known complete "Zuo Zhuan" manuscript is the "ancient manuscript scroll" preserved at the Kanazawa Bunko Museum in Yokohama, Japan.
