Perhaps you should try some spelling variations:
hyoung yang » kyoung yang
min hyoung » min hong, mun young
chen yang » chen rong
song saur » kong sar
yang hua » wang hua, yang hui, ying hua
ren yang » ren yan, dan yang, pei yang
wong sau » wong sam, wong siu, wong shiu

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

• Performing a fuzzy search may retrieve terms with similar spellings: min hyoung yang hua ((ren yang) or (chen yang)) john ((song saur) OR (wong sau)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: min hyoung yang hua ((ren yang) OR (chen yang)) john ((song saur) OR (wong sau)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "min hyoung yang hua ((ren yang) or (chen yang)) john ((song saur) OR (wong sau)) ;*".
