larded school was put forward by Li Zongwu in 1917 at the beginning of the Republic of China, which preached that the skin should be as thick as a city wall and the heart should be as black as coal, so as to become a "hero". He cited Cao Cao, Liu Bei, Sun Quan, Sima Yi, Xiang Yu, Liu Bang and other figures as examples, trying to prove his larceny and enumerating how their thick skin and black and white heart affected their success or failure. Laroche reflects the dark and selfish side of human nature from a certain angle, but it also reflects people's way of life. Although larded school was originally a playful theory put forward by Li Zongwu in a mocking way, it unexpectedly aroused a warm response, and almost became one of the modern prominent schools. It also made Li Zongwu a master of larded school, and was later hailed as one of the "2 wizards and eccentrics who influenced China culture".

the method of larded learning is simple, but it is wonderful to use. When Liu Bang and Sima Yi have finished learning it, they will unify the world. Cao Cao and Liu Bei, each of whom has mastered half, can also be called lonely and independent; Han Xin and Fan Ceng also mastered half of each other. Unfortunately, they were born at an untimely time. It happened that they were born in the same era as Liu Bang, who had both black and strong personalities, and they all failed. However, when they were alive, they won the princes and princes by virtue of their unique skills in larceny, and for a while, after their death, Shi Chuanzhong also occupied a place, which shows that larceny still lives up to people!

The Big Black Collection collects important papers and monographs of Li Zongwu, and you can get a complete picture of the author's thoughts by looking through the whole book. As far as academic value and historical position are concerned, Jorge Posada, Jorge Posada's Principles (Psychology and Mechanics), Jorge Posada, China's Academic Trend and Discussion on Social Issues are Li Zongwu's representative works.

unlike the later versions, the original larded school did not have the so-called "larded classics" and "larded biography", but was an article in classical Chinese style, and many of its sentence patterns were copied from Confucian classics. This classical Chinese style is the only article in Li Zongwu, and all kinds of later works on larceny and all kinds of shoddy larceny after 1949 are all based on it.

The book takes the masterpiece "Larceny" of Taipei Library as the base, and arranges and publishes Li Zongwu's complete manuscript for the first time. From between the lines, we can really understand the essence of Li Zongwu's original "Larceny".
