Qianlong Bao Tong refers to the copper coins manufactured and issued during Qianlong period of Qing Dynasty. The first year of Qianlong was 1736, so the earliest Qianlong Bao Tong has been 286 years.
In the 13th year of Yongzheng (1735), Emperor Gaozong ascended the throne in the Qing Dynasty and changed to Qianlong. Casting "Gan Long Bao Tong" still needs a minute and twenty cents, and the foundry workers in Shufa Qian are more particular than those in Yongzheng. At first, the Qing government continued to implement the deflation policy. Compared with Yongzheng, the money bureau increased and decreased. First of all, after four years of Qianlong, the third bureau of Baohe, Baogong and Baoji was stopped. After five years of Qianlong, Fu Bao Bureau was opened, Guibao Bureau was opened in seven years, and Baozhi Bureau was opened in ten years.
