Why do hotels have foreign currency exchange?

This is one of the national star hotel evaluation standards, because our hotel will receive foreigners and we provide this service for the convenience of our guests. But it is of little practical significance. Although many hotels have foreign currency exchange on their signs, they cannot actually exchange it because the country's foreign exchange management is also very strict and it is actually very difficult to operate. It is recommended that guests can also exchange money at Bank of China, the airport, etc. Hope this helps you
