In the first year of Kangxi, the Qing government ordered to stop casting "Shunzhi Tongbao" money of the previous generation, but to cast "Kangxi Tongbao" money instead, and stipulated that in the future, all successors should be changed to yuan, as was the case with the casting system. According to the back text, it can be divided into two categories: one is Manchu money imitating the "Shunzhi Four Styles". Qian recited the Manchu "Baoquan" and "Baoyuan" left reading, which were created by Hu and Gong. The other is Manchu-Chinese money imitating Shunzhi Five Styles. At that time, 24 money-making bureaus were set up in the whole country. Due to the influence of the problems of foundry cost and coin-making, each Wen Kangxi coin once weighed four cents, one cents and seven cents respectively, which resulted in three kinds of "Kangxi Tongbao" coins with different weights, i.e. large, medium and small. The coins coined by different coin-making bureaus are different. From the front words of the 24 coins, there is no big difference. They are all Kangxi Tongbao. Their backwords are different. Except that Baoquan Bureau and Baoyuan Bureau are Manchu, the other 22 coins are in Manchu and Chinese, with Manchu on the left and Manchu on the right. These 22 Chinese characters represent 22 coin-making bureaus. If the subdivision version, there is also a Kangxi "Luohan Qian". "Luohan Qian" is a kind of birthday money for Emperor Kangxi's 60th birthday. Kangxi was the oldest emperor in Qing Dynasty. It lasted for 61 years. In March of Kangxi's 52 years (1713), it was his 60th birthday. Baoquan Bureau of the Ministry of Special Household Affairs (then the mint) precisely coined a batch of "Longevity coins" as birthday commemoration. The back of the coin was the word "Baoquan" in Manchu, which means that Baoquan Bureau of the Ministry of Hubu in Beijing was made. The coins of Qing Dynasty have always been loved by people in the coin collection market, especially the coins of the two emperors Kangxi and Qianlong. The coins of Kangxi and Qianlong were collected by most people and they were unwilling to be sold again, which led to the faults in the collection market.
