hi dude 
improve english huh?
try this:
--------
Hi everybody (one word). I'm 18/m. I am from China. I am now
studying in Singapore (you are currently doing so therefore the
continuous tense is best, and it's not good to use abbreviations in
formal English).
I would like to make some friends ("make friends" is better suited
when compared with "know friends"; they mean different things) and
train my grasp of the English Language.
--------
hope you have a good time here
