Others will definitely not be able to do it. Generally, foreign banks require you to handle it in person. The easiest way is to go to Hong Kong to apply. There is no other way. It cannot be done by an agent. Hong Kong requires that the bank card must be applied for in person, and proof of address, such as a credit card statement, must be provided. It's very strict. I've asked many questions, but it can't be done even with money.
