 As the Northern and Eastern Circuits of Xinjiang were mostly inhabited with bartering nomads who didn't have a monetary tradition the government of the Qing dynasty didn't force these peoples to adopt the monetary system of China.These regions also saw an influx of immigrants from China proper who brought with them their own money and in the Eastern Circuit the local population had already adopted the Chinese monetary culture prior to its conquest by the Qing dynasty so these two circuits would use the same type of cash coins as were used in China proper and didn't have to adopt a completely different monetary system.Cash coins from China proper flowed in large numbers to these regions.
