Filial piety is considered the first virtue in Chinese culture, and it is the main concern of a large number of stories. One of the most famous collections of such stories is The Twenty-four Filial Examples(Ershi-si xiao 二十四孝). These stories depict how children exercised their filial piety in the past. While China has always had a diversity of religious beliefs, filial piety has been common to almost all of them; historian Hugh D.R. Baker calls respect for the family the only element common to almost all Chinese believers. These traditions were sometimes enforced by law; during parts of the Han Dynasty, for example, those who neglected ancestor worship could be subject to corporal punishment.
