It was written in imitation of the archetype Sanzijing 三字經. The first chapter describes the construction of the cosm and society, including the inferior position of women to men. The second chapter explains how a girl has to behave before being married. Foot-binding is mentioned here, and obedience to the parents is a very crucial point.
