Is there an express stipulation in Hong Kong that hotels booked by credit card cannot be changed or cancelled?

Because the hotel has signed a contract with the travel agency, it is customary not to cancel the change of hotel reservation in Hong Kong. In general, you can't cancel the room that has been booked successfully, and you can't modify the name and date of the reservation. Even if it is cancelled, there will be no check-out fee, and at the beginning of the reservation, it will always be explained to the customer that after the reservation is successful, it cannot be cancelled or changed, but in some non-artificial and unpredictable special circumstances. For example, the volcanic eruption caused the airport to be completely grounded and it was impossible to arrange the trip. You can let the travel agency communicate with the hotel to see if there is any special treatment. You should try to apply for communication because you have been told in advance that you can't cancel this agreement. Hotel prices in Hong Kong are different almost every day, and the date cannot be changed (including some problems in the industry). All travel agencies operate in this way. You can't change this big environment alone, so you must check whether your and your family's documents are wrongly booked before booking, and don't change them casually after booking.
