In the thirteenth year of Yongzheng (1735), Emperor Gaozong of the Qing Dynasty acceded to the throne, and changed the yuan to Qianlong. For casting "Ganlong Tongbao", it is still required to weigh one penny and two cents. The Shufa Qian foundries are more exquisite than those in Yongzheng. At first, the Qing government continued to implement the policy of deflation. Compared with Yongzheng's, the amount of money increased or decreased. First of all, in the fourth year of Qianlong, the three bureaus of Baohe, Baogong and Baoji were stopped. In the fifth year of Qianlong, the Baofu Bureau was opened, in the seventh year, the Baogui Bureau was opened, and in the tenth year, it was opened. Before the Qianlong Dynasty, money was made of copper, lead and zinc without tin, and it was called "yellow money". In the fifth year of Qianlong, it was stipulated that 2% tin should be added to the copper material for casting money, which was called "green money". Officially, it is to put an end to private money, but in fact it is tantamount to losing weight. "In the 40 years of Qianlong's reign, the situation of private casting became more and more prosperous, and the provincial officials stole the casting. The government could do nothing about it. In addition, the copper production in Yunnan was decreasing year by year, which led to soaring copper prices and the cost of casting money. The Qing government then adopted the deflation policy, stopping the casting of Baozhi, Dali, Guangxi and Lin 'an bureaus successively, and encouraging businessmen to import copper materials from overseas. However, these measures failed to solve the problem fundamentally. Although private investment decreased, official money did not increase, and private transactions lacked money, so the phenomenon of using ancient money appeared. Fifty years after Qianlong's reign, Baozhi and other bureaus were opened one after another, and at the same time, the standard of money making was relaxed, which led to the uneven quality of money making in the late Qianlong period, which was not as good as the first. In addition, during the Qianlong Dynasty, the "Ganlong Tongbao" red money (also called Poole money, which means money in Uyghur language) was produced in Xinjiang, and it was cast in Xinjiang with copper produced in Xinjiang as raw material. Since then, all dynasties have cast it.
