The text dates from the 4th century BC to 3rd century BC. It is not known who actually wrote the document. It is attributed to a conversation between Confucius and his disciple Zengzi. A 12th-century author named He Yin claimed: "The "Classic of Filial Piety" was not made by Zengzi himself. When he retired from his conversation (or conversations) with Kung-ne on the subject of Filial Piety, he repeated to the disciples of his own school what (the master) had said, and they classified the sayings, and formed the treatise."
