The admins at Fung Forever (his official fanclub) has just posted this message on their forum:

As we know there’re many overseas fans who wish to send letters/gifts to ar Fung, FF has especially set up a post office box, allowing everyone to send the letters/gifts there. The FF committee will pass these onto Fung’s hands!

From 8th July 2008, if everyone has letters/gifts for the committee to pass onto Fung, you can send them to this address:

P.O. Box No. 1205
Shatin Central Post Office
Attn: J.Y. Tam

Please note: Letter/parcel must state “Shatin Central Post Office” and “Attn: J.Y. Tam”, otherwise they will not be received! (If the letter/gift is for Fung, can add (Fung) after J.Y. Tam, if the letter/gift is for FF, can add (FF) after J.Y. Tam.)

Joey from FF has confirmed that you can send letters/gifts to this address even if you are not a FF member.

THANKS FF!!! ^^
