唔係好識點郵寄

Buy a pack of envelop in bookshop.
Then,put your paper which you want to send into an envelop.
After that,buy a stamp /some stamps from the post office.It depends on the
weight of your litter.
Finally,you can put it in a mail box.
The end

Sorry,it should be letter,not litter. :-)

一般信件本地$1.4,如果要郵寄公文袋信件,要去郵政局秤下有幾重才買郵票.
