Since the reform and opening up, with the sustained, healthy and rapid development of the socialist market economy, the social demand for cash is also increasing. The design and printing of the fourth set of RMB were limited by the conditions at that time, and there were some shortcomings, such as simple anti-counterfeiting measures, which were not conducive to the anti-counterfeiting of RMB; Lack of machine-readable performance is not conducive to the automatic processing of banknotes and so on. These all need to issue a new version of RMB in time.
