Perhaps you should try some spelling variations:
yang hyoung » wang hyoung, kang young, hwang byoung
huang yang » huang ying, huang chang, wang yang
hyoung di » hyoung il
wong shiu » wong siu, cong shu, song shin
kaw than » know than
hong shu » cong shu, tong shui, hong seo
hong ghi » zhong zhi, hong g, hong hai

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: huang yang hyoung di (ren OR rent) kaw than ((((hong shu) OR (wong shiu))) OR (hong ghi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "huang yang hyoung di (ren or rent) kaw than ((((hong shu) OR (wong shiu))) or (hong ghi)) ;~".
• Adding a wildcard symbol may retrieve word variants: huang yang hyoung di (ren or rent) kaw than ((((hong shu) OR (wong shiu))) or (hong ghi)) ;*.
