The specific area where you use the collection account depends on the area where your admob account is registered. If it is a country or region, only domestic collection accounts can be used. Remember to open a dollar account. If it is American, you can only use an American card to collect money. Go to admob backstage and add a collection account to see it.

In addition, if there are conditions, I personally suggest registering an account in the port area or the United States. Otherwise, if the account in a country or region receives money, it needs more than 150 USD to make a payment to you, and the threshold is relatively high. The collection account in Hong Kong is relatively simple. Go to Hong Kong, or now many first-and second-tier cities also have cooperative banks that can handle Hong Kong cards. If it is inconvenient, you can also find a third-party collection company such as Ping Pong, which is also cost-effective.
