Classic of Filial Piety
In the postface to the "Kongzi Jiayu", its author describes the collection as discussions Confucius had with his disciples and others, recorded by his disciples. Selected discussions were published as the "Analects" ("Lunyu"), while the rest was collected in the "Jiayu". This characterization is consistent with the content of the "Jiayu", which contains nearly all the Confucian lore found in such diverse ancient texts as the "Zuozhuan", "Guoyu", "Mencius", "Han Feizi", "Book of Rites", "Han Shi Waizhuan", "Lüshi Chunqiu", "Huainanzi", etc., except what is included in the "Analects", the "Classic of Filial Piety", and a few other works.
