Any bank will do. Zhaoyuan is a county-level city under the jurisdiction of Shandong Province, which is managed by Yantai City and located in the northeast of Shandong Province. The fourth set of RMB can be exchanged at the business outlets of banking financial institutions. Any bank in Zhaoyuan can exchange the fourth edition of RMB. The fourth set of RMB has been in circulation for more than 30 years, and its anti-counterfeiting technology still stays many years ago, which obviously lags behind the social and economic needs. After the issuance of the fifth set of RMB, the issuance of the fourth set of RMB bonds only accounts for less than 1% of the RMB issuance, and most of them have been damaged or in a state of precipitation. So the country stopped circulating and opened up exchange.
