Di Zi Gui was written in the Qing Dynasty during the reign of the Kangxi Emperor (r. 1661-1722) by Li Yuxiu. The book is based on the ancient teaching of the Chinese philosopher Confucius that emphasises the basic requisites for being a good person and guidelines for living in harmony with others.

As translated by James Legge:
A student should show filial piety at home and respect people outside behave prudently and trustfully love all universally and draw close to sages. While he has energy to spare he should study edification by the sage.
