The "Gaochang edition" 高昌本 was a text written by Tanjing 曇景, explaining the method of conferral of bodhisattva precepts as practiced at Gaochang. Funayama suggests that the background to this text might lie in political connections between the Juqus, after their expulsion from Guzang, and the South. "It is not unthinkable to suppose that Tanjing, a monk from Gaochang, was sent on a political mission to the South. At some period around the middle of the fifth century, he moved from Gaochang to Jiankang and gave oral instructions concerning the method of receiving the bodhisattva precepts which had prevailed in Gaochang among the followers of Tanwuchen [= *Dharmakṣema]." Funayama refers to his own more detailed treatment of the same text, Funayama (1995): 32 ff.
