Perhaps you should try some spelling variations:
chung kang » chung kay, chung tong
wing diana » wing ian
twinn ian » wing ian
chan fong » chew fong, chan eng, chan ming
chan kang » chan eng, chan jan, chan ming
colin xu » colin c, colin _
xu chan » mun chan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing diana) OR (twinn ian)) colin xu chan fong ((chan kang) OR (chung kang)) yam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing diana) or (twinn ian)) colin xu chan fong ((chan kang) OR (chung kang)) yam ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing diana) or (twinn ian)) colin xu chan fong ((chan kang) OR (chung kang)) yam ;*.
