Central bank's eight-character policy

The fourth set of RMB banknotes issued by the People's Bank of China ceased to be used in circulation on May 20 19, and the new version of RMB banknotes has a one-year exchange period, that is, it can be exchanged in banks before April 30, 20 1 9, and it will be invalid when it expires. Today has passed the exchange period. I wonder how old your 1980 paper money is. New banknotes can be put away for future appreciation. Some people will buy old banknotes in a few years, and the price may be lower, but it is better than invalid.
