Jijiupian
The (c. 40 BCE) Jijiupian 急就篇, which was compiled by Han dynasty scholar Shi You 史游 (fl. 48-33 BCE), was a Chinese primer and a prototype for Chinese dictionaries. This Chinese character abecedarium contains a series of orthographic word lists, categorized according to character radical, and briefly explained in rhymed lines. In the Qin and Han dynasties, several similar othographic primers were in circulation, such as Cangjiepian, but the Jijiupian is the only one that survived for two millennia.
