Perhaps you should try some spelling variations:
dang hung » dang cuong, fung hung, ming hung
yang yang » wang yang, wang yan
chan fong » chew fong, chan kang, chan ming
yang hua » wang hua, yang hui, ying hua
chan eng » chan kang, chan ming, han en
tong hui » wang hui
rene » rent, gene

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (yang di)) ((yang hua) or (dang hung)) rene ((chan fong) OR (chan eng)) tong hui ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (yang di)) ((yang hua) OR (dang hung)) rene ((chan fong) OR (chan eng)) tong hui ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang di)) ((yang hua) or (dang hung)) rene ((chan fong) OR (chan eng)) tong hui ;*".
