Lv Buwei's Historical Contribution:
1. Write "Lv Chunqiu": When in power, ask the ministers to write "Lv Chunqiu" together. In the works of a hundred schools of thought contend, Lu's Spring and Autumn Annals is listed as a saint, in which "miscellaneous" refers to a lot of content, including many things, absorbing the strengths of many cultures and linking them with a unified thought.
2. Contribution to the war: Lv Buwei resolutely opposes indiscriminate massacres in the war, especially the humane treatment of prisoners of war. It is also suggested that when entering other countries in the war, don't destroy crops planted in other people's fields, don't rob other people's pigs, cows and horses, don't burn down ordinary people's houses and houses at will, don't look at trees by the roadside, and don't dig other people's graves.
3. Stabilize the country: At that time, Qin had many heirs to the throne. Lv Buwei was worried that civil strife would attract foreigners for a long time, leading to internal troubles and foreign invasion, so he persuaded everyone to take back the proton alien of Zhao and made him a prince, thus preventing civil strife. As an assistant to the Prime Minister, Lv Buwei managed the State of Qin strongly, which laid a very solid foundation for Qin Shihuang to unify the Central Plains.
