when Qin Shihuang first succeeded to the throne, the first emperor respected his mother, Zhuang Xiang, and later became the queen mother, and Lv Buwei as the prime minister, so he was called "Guanzhong". Because the government was young and early, all state affairs were entrusted to Wei.
Don't use politics, pardon sinners, make contributions to the former king, be kind to the people, make more guests, recruit talents and scholars, accept Li Si as a shed, accept Zheng State to repair water conservancy, use Meng Ao as a general, send troops to attack Korea, Zhao and Wei, destroy the Eastern Zhou Dynasty, take Han Zhicheng and Xingyang, and set Sanchuan County; He took the twenty cities of Wei, set up the East County, and moved Weijunjiao to Yewang (now Qinyang City, Henan Province) as a vassal. Extending thousands of miles laid the foundation for Qin to unify the six countries.
at the end of the warring States period, there was a trend of welcoming guests and writing books. Lv Buwei, with the strength of Qin, was ashamed. He recruited all the wise men in the world and gave them a generous salary, reaching 3, diners. At that time, Xunzi and others had written books and distributed them all over the world. If you don't, everyone will hear about it. The collection theory is thought to be eight readings, six readings, twelve periods, 16 articles, and more than 2, words. It is called "Lu's Spring and Autumn Annals" and also called "Lu Lan".
Lu's Spring and Autumn Annals was written in about 239 BC. It is mainly based on Confucianism and Taoism, and it also includes the theories of the pre-Qin schools, including fame, law, ink, agriculture and Yin and Yang, and prepares for the ancient and modern events of all things in the world, which concentrated on expressing Lv Buwei's political views and laid the ideological foundation for Qin to unify the world. According to legend, after the book is completed, it hangs in the country, and those who can increase or decrease a word will be given a thousand dollars. It can be seen that this book is cautious.
Lv's Spring and Autumn Annals is more valuable in retaining important parts of pre-Qin agricultural books. In this book, four articles, namely, Going to Agriculture, Rendi, Debating on Soil and Examining Time, are devoted to agriculture. It not only discusses the importance of developing agriculture and agricultural decrees, but also talks about many agricultural technical problems. Advocate intensive cultivation and intensive cultivation; Pay attention to the countryside and sow properly; Strengthen farmland management, thinning seedlings, weeding and pest control; Carry out terraced fields, drain and wash soil, control saline-alkali soil and attach importance to the reform of farm tools. At that time, although Niu Geng and Tieji were not popular, they were already used. Advanced production tools greatly stimulated farmers' enthusiasm for production. Four papers, such as Shangnong, should be regarded as the oldest existing agricultural books in China and important materials for studying the development of ancient agriculture in China.
