There were two kinds of Gyochukokyo, one being "Kaigenshichubon" (annotated edition by Genso), which was written in 720, and the other being Tenhojuchubon (revised edition of Kaigenshichubon), which was revised in 743 and distributed three years later; however, only the latter remains in existence.
開元10年（720年）に著された開元始注本と天宝(唐)2年（743年）に改訂して3年後に頒布した天宝重注本の2種類があるが、現存しているのは後者である。
