Technical backbone Li Ming spent all his money to help his friend Zhao Jianguo save the machinery factory that was on the verge of bankruptcy. He provided money, technology, attracted customers, and even drank until his stomach bleeds. However, as soon as the factory made money, Zhao Jianguo, instigated by his wife Zhang Xiumei, kicked Li Ming away with 40,000 yuan. Li Ming left calmly and turned around to found "Integrity Machinery Factory". In pursuit of huge profits, Zhao Jianguo and his wife switched to using inferior raw materials and found unscrupulous OEMs. As a result, product quality collapsed, customers were lost, and the factory was closed. Li Ming became the biggest winner with his excellent technology and the principle of "being conscientious and doing things with integrity".
