C fu said the back door has to be "dup" as it's 凹左 but can't see at that night...maybe it's too dark...luckily i have discussed the compensation amt with him at that night...
just take a form from any retail banks and fill in the personal data and then send it back to the bank (if he wants to deposit in HSB, you need to send the form back to the destinated bank which is HSB in this case).
