Hello, gift cards from AppStore’s Hong Kong area cannot be recharged to accounts in the US area.

The cards in the port area can only be recharged in the port area. If you want to recharge in the US area, you need a foreign currency credit card. (Of course, you can also buy redemption codes on a certain treasure. Many people use them. It’s no problem, but there are also thunderstorms.) If you don’t have a credit card, just activate one online. I used the most common full-currency merchant credit card issued by Visa. 1. Select the gift card on the official website. Pay attention to the recipient's email address. It must be written correctly. This is just the email address used to receive the redemption code. It is best to use Gmail. 2. Then to settle, you need to fill in your credit card information and billing address. The billing address can be generated online by finding a random address in the United States. After my test, there will be no tax deduction, so whether it is the address on the US ID or this , you can fill it in casually. 3. You will then receive three emails. The second one contains a gift card. You can get the redemption code from it and go to the app store on your mobile phone or computer to redeem it and recharge it.
