Getting a Hong Kong card is simple, but the most important point to remember is:

Absolutely do not use HSBC, Standard Chartered and other banks to receive funds from the crypto world, you will eventually get your account banned!
These banks are great and should be cherished; they are essential in certain scenarios.

You can use payment methods like ZhongAn and MOX, and then even enter the stock market and come out later to go to HSBC.
