How to punish reactionary slogans

For such RMB, banks must treat it as broken currency and must not circulate again.

RMB is the legal currency of our country. Scribbling on RMB is prohibited by the "Regulations of the People's Republic of China on the Administration of RMB." If you receive such RMB with reactionary slogans printed on it, you can report it to the public security agency and then take it to a bank business hall to exchange it for cash of equivalent value. After the bank recovers such RMB, it will be treated as damaged currency and destroyed in accordance with the law.
