Teaser quote: An important nobleman in the south once read a defective copy of the commentary on “The Rhapsody on the Shu Capital.” In the gloss “The ‘squatting owl’ refers to yam,” “yam” (yu) is mistakenly copied as “lamb” (yang). Then someone gave the nobleman some lamb, and he wrote back saying, “Thank you for gracing me with the squatting owl.” The entire court was shocked, having no idea what it meant. Only much later did people manage to trace the error and come to understand.
