韩婴, a scholar at the courts of Emperors Wen and Jing, founded the Han school of the
诗经, one of three officially taught readings of the Songs. His "inner commentary" is lost; this "outer" one, which uses lines of the Songs to sum up moral tales, survives in ten scrolls. The rival
毛诗 school won out, and its text is the Book of Songs read today.
