What does counter-propaganda refer to?

Counter-propaganda refers to RMB with reactionary propaganda slogans printed on it. This kind of RMB is used by cult organizations to spread propaganda with reactionary political content. This behavior is the use of RMB for reactionary propaganda, which violates national security and social management order, and is a serious illegal and criminal act. If you receive this kind of money, you should reject it directly or exchange it for equal amounts at a bank outlet to prevent it from continuing to circulate in the market. Once you find someone printing reactionary propaganda on RMB, you should call the police immediately. Counter-propaganda materials are extremely harmful to social harmony, national security and people's ideas and concepts, and must be severely cracked down and cleaned up, and cannot be circulated.
