Emperor Chengzu and imperial filial piety of the Ming dynasty

Historically, the concept of “filial piety” was already well developed as early as the Zhou dynasty. ¹ During the chaotic and turbulent Spring and Autumn Periods, the Confucian school advocated “rectification of names,” proper human relationships, and that rulers relieve the people's agony. For them, the idea of filial piety enjoyed a primary position of importance.
