Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang dong » yang yang, yan cong, jeng dong
hua irene » hua ren
sang minh » kang minah, song min, song ming
dong hua » wang hua, tong hui, dong hoi
yan minh » tuan minh, yang mind, yuan ming
hong hai » shang hai, zhong tai, dang hai
hong yu » wong yue

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: wang yang dong hua irene ((((yan minh) OR (sang minh))) OR (anh minh)) ((hong hai) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang dong hua irene ((((yan minh) OR (sang minh))) or (anh minh)) ((hong hai) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang dong hua irene ((((yan minh) OR (sang minh))) or (anh minh)) ((hong hai) or (hong yu)) ;*.
