Lv Chang, the minister of the Yuan Dynasty, was the best at managing money. When Zhu Yuanzhang, the emperor of the Ming Dynasty, was in power, he sent Lu to Jinling, Zhu's base area, and invited Zhu and Zhu Aicai. He invited Lu, recruited him as the senior minister of the Ministry, stayed with him and "raised" him. After the founding of the People's Republic of China, this minister managed Daming's finances and really kept Daming in good order. Only later, Zhu suspected that he was an important official and was murdered. Because he had mastered the criminal evidence of Zuo Cheng and yang xian, he was framed by yang xian, and the old man who was nearly seventy years old was sent to guard the border and the typhoon shelter. Almost killed by Yang Xian's partner on the way. Fortunately, he was extremely clever and expected Yang Xian's trick to save Lu.
