Perhaps you should try some spelling variations:
chan kang » chung kang, chan eng, chan jan
chan fong » chew fong, chan eng, chan ming
doing un » doing und, doing our, doing von
plan how » plans how
hung seo » hong seo
wing un » wing sun, being un, wing ian
hung ho » gung ho, sung ho

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 un) OR (doing un)) plan how best ((chan kang) OR (chan fong)) ((hung seo) OR (hung ho)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing un) OR (doing un)) plan how best ((chan kang) or (chan fong)) ((hung seo) or (hung ho)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing un) OR (doing un)) plan how best ((chan kang) or (chan fong)) ((hung seo) or (hung ho)) ;*.
