CCB can exchange foreign currency. You can exchange US dollars into RMB at the branch outlet where you open an account (please refer to 95533 for details). If necessary, please bring your valid ID card and foreign currency deposit account to CCB outlets. It should be reminded that the State Administration of Foreign Exchange implements the annual total management of individual foreign exchange settlement, and the annual total is equivalent to 50,000 US dollars per person per year.

There are certain risks in storing foreign currency. If a currency circulates abroad, its circulation rate will decrease, and the quantity in its official circulation area will also decrease. In this case, its official central bank will be forced to increase the number, which will lead to the devaluation of the currency under certain conditions. For example, in 2002, the dollar depreciated 15% against the euro in a short time, which led to the depreciation of the euro zone's dollar foreign exchange reserves.
