Reasons for learning ancient books and recommending books

"360": In the early years of Zhenguan in Li Shimin, Emperor Taizong ordered admonishers Wei Zhi and Yu Shinan to sort out the historical materials of emperors' governing the country in past dynasties, and extracted the essence of self-cultivation, keeping the family in order, governing the country and leveling the world from the Six Classics, the Four History and the contention of a hundred schools of thought, and compiled it into a book. From the beginning of the Five Emperors to the end of the Jin Dynasty, from more than 14,000 volumes and 89,000 volumes of ancient books, it was compiled in the fifth year of Zhenguan (63 1), with a total of 65 volumes of about 500,000 words, and it was named Guanshu, which means that governing the country must follow. This book is not only an important theoretical basis for Wei Zhi to remonstrate with Emperor Taizong, but also the ideological source and administrative reference for Emperor Taizong to establish "Zhenguan Rule".
