I dont' understand the reply from those guys (Legionee - 未式知"車"係點樣就想去賽車, lionxxx - 唔識點入....真係唔夠資格買鎗). It's really nonsense and I feel so sorry to say so. Anyway, I quite agree with Ethan_meu's comment and everyone will start from knowing nothing. What's wrong with it and please behave yourself as a gentleman.
