Basically, it is enough for me to change at the airport and take a small train to the hotel. Generally, it is 100 RMB, or I can directly swipe my card on the plane to buy a small train ticket.
VISA can be used directly in the hotel. Many times when I go shopping, I use the UnionPay channel, which can save a little exchange rate loss! Many shopping emails have places to exchange Malaysian ringgit. I often change some Malaysian ringgit at India point near the subway station, and the exchange rate changes every day. During the appreciation of RMB, I feel that RMB is more valuable every day! ! !
