The original name of Jing Sheng should be Augmented Xianwen, which is an enlightening bibliography for children in ancient China. Also known as "ancient sages" and "ancient and modern sages". The title of the book was first seen in the drama Peony Pavilion in the Wanli period of Ming Dynasty, so it can be inferred that this book was written in the Wanli period at the latest.
Later, it was changed to this appearance after the continuous supplement of literati in the Ming and Qing Dynasties. It was called "adding glory to the text" in history, commonly known as "adding glory to the text". I haven't seen any books, except that the Confucian scholar Zhou revised them during Tongzhi period in Qing Dynasty, so it is probably the crystallization of folk creation.
Extended data:
The contents of augmented virtuous essays are as follows: first, talk about people and interpersonal relationships; The second is to talk about fate; Third, fickle, too poor to love the rich, so the world is full of traps and crises. In the article, a lot of emphasis is placed on fate and retribution, and it is believed that everything in a person is arranged by fate, and people have to do good things to have a good chance.
Augmented sages have a lot of space to describe how to treat people, which is the core of the full text. There are many descriptions of tolerance in this paper, and it is considered that tolerance is the way to eliminate troubles and sins. While advocating self-protection, caution and tolerance, it also emphasizes people's subjective initiative, which is considered as the principle of doing things. There is no lack of persuasion in the article that "it is indispensable to harm others and to prevent others".
