Lv Buwei met Qin proton. After coming back, he said to his father, "How many times is the benefit of farming?" Say, "Ten times." How many times did Zhu win? "How many times have you been the master of the country?" Yue: "Countless." Yue: "I worked hard in the fields today, so I can't warm my clothes and eat more;" Today, the establishment of People's Republic of China (PRC) and monarch can leave the world behind.

Puyang people were doing business in Handan, the capital of Zhao State, and saw the son of Qin State taken hostage in Zhao State. After returning home, he asked his father, "How many times can you earn by farming?" Father said, "Ten times." He asked, "How many times can you earn by selling jade beads?" Father said, "A hundred times." He also asked, "How many times can you gain by establishing a king of a country?" Father said, "That doesn't count." Lv Buwei said: "Now farmers are working hard to plow the fields, but they can't get enough food and clothes;" If we build a country and a monarch, the profits can be passed on to future generations. The son of Qin made people hostage to Zhao. Living in Handan, I am willing to work for him. "
