Lu Buwei (? - 235 BC) was a native of Puyang in the late Warring States period. He was originally a wealthy businessman in Yangzhai. He met Qin's protégé in Handan and supported him with all his money and helped him return to Qin and succeed to the throne. He became King Zhuangxiang. He was granted the title of Marquis by the Prime Minister and lived in Luoyang for 100,000 households. After the death of King Zhuang Xiang, he assisted the young master Yingzheng, respected as "Second Father", and took charge of the government for more than ten years. During his reign, he destroyed the Eastern Zhou Dynasty, established Sanchuan County, and expanded Qin's territory; he implemented the policy of equal emphasis on virtue and force to lay the foundation for unification. He gathered three thousand disciples to compile "Lu's Spring and Autumn Annals", which integrated Confucianism, Taoism, Mohism and other schools of thought, and pioneered the "Miscellaneous Family" theory. He hung a book in Xianyang Gate saying "One word for gain or loss will reward you with a thousand pieces of gold". Eventually, he was implicated in the Lao'ai Rebellion, so he resigned and moved to Shu, where he drank poison and died. He managed the country through business and governed the world through culture. His life can be called a legend of the Warring States Period.
