Buying gift cards for hong kong?

Well it does say china in global sectiion i guess but why a china location and a global one as well thats really confusing. Other thing that is confusing me is Why does bambu lab have china in there but can only add 1 gift card per orders ?? Are you doing this because you dont want china to grow as big in bambu lab ?
I’m guessing they aren’t trying to grow the china market as much as foreign markets
