The Confucian classics have been engraved on stone tablets several times. The Xiping Stone Classics or Han Stone Classics were set up at the Imperial Academy outside Luoyang in 175–183. Around 200,000 characters were inscribed on 46 stelae, comprising the text of the seven classics recognized at the time: the "Book of Changes", "Book of Documents", "Book of Songs", "Book of Rites", "Spring and Autumn Annals", "Classic of Filial Piety" and "Analects". Only a few fragments of these tablets have survived. The Zhengshi () classics in 241 recorded three classics in three scripts, but these have since disappeared.
