You don't need to go to Hong Kong to copy Hong Kong stocks, just open them in the mainland. The materials you bring are ID card, bank card and residence certificate. Some brokers don't need residence certificates. Take these materials to the local business hall to apply for opening an account (mainly write a few forms). After the application, the brokerage company will send your information to Hong Kong for review. Generally, Hong Kong will call you a week later to confirm. I will send you your account number by email. The broker will also give you the remittance address and account number, and then you can remit money at the counter according to the address. It usually arrives on the same day. If you want to withdraw money, apply to the brokerage firm, and then the brokerage firm will transfer your money to your designated account. I hope it helps you.
