First of all, make sure what kind of platinum card you have. To be sure, overseas use is definitely free of annual fees for life. Now that RMB is going to be internationalized, BOC is the main bank that has signed RMB swap agreements with other countries, so we are encouraged to use foreign currency. Under normal circumstances, another platinum card used in China should be free of annual fees in the first year, and after reaching the number or amount of consumption in the second year, it should be free of annual fees or redemption points. I haven't heard that the domestic card said free for life at the beginning.

If you have other specific questions, I suggest you call the customer service staff of the bank. I hope I can help you. Thank you.
