Can you help me explain the concepts of Changping, Hong Qian and Baoquan, and where to identify their traces on copper coins?

1. "Changping style" originally refers to the word [pass] [guarantee] of some currency clearing bureaus (mostly the bureau of protecting the Soviet Union and a few bureaus of protecting philosophy), which is very similar to the [Changping style] of North Korea and is called "Changping style".

2. The "routine" we are talking about now must be a "regular hand", with a large range. It refers to:

1. "Positive" money begins in Qianlong. The "official" money in the year number of Qianlong is not just a game of Bao Su.

2. While Jiaqing Daoguang Xianfeng Tongzhi Guangxu1* * 6 Dynasty, only Baosu Bureau cast money to continue its money. The casting style of the money is called Changping style.

Red money refers to small flat money made of red copper by various casting bureaus in Xinjiang in Qing Dynasty. (Money in Ming and Qing Dynasties was mostly brass)

(3)

In the Qing Dynasty, many casting bureaus were set up in various provinces, such as the Hubu-Baoquan Bureau; Ministry of Industry-Baoyuan Bureau; Baoji Zhili-Baozhi Bureau; Henan-Baohe Bureau; Fujian-Fu Bao Bureau; Gansu-Baogong Bureau and so on. The back of each piece of money is written in Manchu for identification.
