Do I need to change Hong Kong dollars to travel to Hong Kong?

If you apply for a pass and visa, you can go to a bank (Bank of China, Industrial and Commercial Bank of China, etc. Banks with foreign currency business can exchange Hong Kong dollars with vouchers. According to the exchange rate of the day, the bank's exchange quota generally does not exceed the cash quota allowed to leave the country, and the price in the bank is more reasonable and reassuring than that in other places.
