astro, actually when i write, i write as dian3, but when i teach tian, i taught her na4 cause i tot that is a na4 u see..
but the word that i write out is a dian4 based on my writing.. alamak..
and i din score A1 for my chinese. haha!!!
when i kena suan1 by tian, i told her,
aiya, this dian3 is so big, i scare that u write it too small then i cannot see, so i ask u to write na4... *actually i was wrong le*
later then i check internet, wah, this tian was right leh.
