I think that, a little over four years after leaving the country, I finally have no bank accounts or any other ties in Hong Kong.

(They just abruptly cut off my ability to log in, but it was following a conversation about closing my account, so I assume that's what they've done. A more explicit confirmation would have been preferred, but oh well.)

I take this as a vindication of "no matter how late, still better than never" :)
