How to ask for response and closing statement in a letter in cantonese and in traditional chinese? I need help in writing a closing paragraph to my letter. What I need to write in cantonese is:

Please, don't forget to reply back my postcard and letter
I'm looking forward to get soon news from you.
Best regards, wish you good luck.


What I tried to do is to translate this using google but it rendered this result:

請不要忘記回复我的明信片和信件
我期待很快收到你的消息。
最好的問候，祝你好運。


Needless to say that I am uncertain if it is right grammatically speaking. To add some insight the recipient of this message is a male. Not sure if it will affect the translation.

Doing a quick research I've found this article which explains that written cantonese lacks of support in google and that is not very used even in Hong Kong (the place to which this letter is intended to be sent). Can somebody help me with this matter?. I really need to do this thing right so that my message can be understood clearly. 

If possible an answer which can be accompanied by a formal version of my message and an informal version would help me the most, of course written in traditional chinese characters.
an informal one:


  Please, don't forget to reply back my postcard and letter


拜託．唔好唔記得回信


  I'm looking forward to get soon news from you


我想早啲收到你嘅消息


  Best regards, wish you good luck


祝安康

about a formal version, well, it's tricky. because, there're "canned" terms for correspondences in chinese, and these terms are in literary chinese.

if you google "尺牘用語", there're numerous pages. briefly, you must know who has superiority, you, or the receiver; then choose the appropriate opening &amp;  ending.

即覆為盼 - hope for your immediate reply

敬請臺安 - for equal status, roughly "wish you calm"

personally, i "write" colloquial cantonese, mixed with english words in email with my friends. these literary chinese terms are simply, "overkill" in context of cantonese.

edited, if the receiver is more important, only use the two below, previous suggestions are not appropriate.

祈請示覆 ~ pray for your reply

祈 kei4　請 ching2　示 si6　覆 fuk1

敬請鈞安 ~ wish you calm

敬 ging3　請 ching2　鈞 gwan1　安 on1

you may click the word to play the sound file :)

the dilemma is, these terms are not colloquial cantonese. i doubt that people would understand, and guess the correct characters when they hear your saying.

c'est la vie, the written chinese is different from the spoken chinese.

anyway, don't misuse "canned" terms for equal, or lower status; it's extremely rude.

last, you may use the 漢語多功能字庫 for learning cantonese pronunciation:

or, if you're using mac os x, the text to speech function is quite good, have a try :)
