「弟子入則孝，出則弟，謹而信，汎愛眾，而親仁。行有餘力，則以學文。」
“The Master said, The young should be dutiful at home, modest
abroad, careful and true, overflowing in kindness for all, but in
brotherhood with love. And if they have strength to spare they should
spend it on the arts.”

The publication of these four texts as a unit in 1190, with commentaries by the Neo-Confucian philosopher Zhu Xi, helped to revitalize Confucianism in China. From 1415 onward, knowledge of Zhu’s commentaries was indispensable to success in civil service examinations.
