That reminds me about those remittance codes I always use when I transfer money to my Taiwanese account:
Most bank employees seem to keep telling that code 510 ( 贍家匯款收入Receipts of allowances to family or relatives ) is perfectly fine and that‘s also what everyone seems to be using.
But I can’t shake the feeling that this actually not the right way to do things and it might cause some trouble at some point in the future…
