Qianlong Tongbao was the currency in circulation during the Qianlong period. During the 6 years of Qianlong's reign, Emperor Qianlong used his strategy of "ruling the country with martial arts" to create the last glorious age in feudal society. After that, it was widely rumored that wearing "Qianlong Tongbao" copper coins could ward off disasters and ward off evil spirits, and it was loved by collectors of later generations because of the homonym "Qianlong".
