楊諒
In the first century AD, Liu Xiang redacted "Xunzi"s extant oeuvre from hundreds of loose fascicles into 32 bundles of bamboo strips. The first commentary on the "Xunzi" does not appear until 818 AD, when an official named Yang Liang claimed to have corrected errors in the existing bamboo strips and transcribed them on scrolls of silk. Yang's commentary still appears in some modern editions of the text. The text has been continuously in print since the invention of the printing press in the 11th century AD.
