Perhaps you should try some spelling variations:
john wong » john song, john bonn
dan yang » daun yang, tan yang, wang yang
jin wong » jin song, jin ying, jin kang
yan han » man han, yan zhang, kang han
han run » han rui, can run, bank run
yi yang » yin yang, yi gang, yu yang
wang » wing, lang

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 OR wan) yan han run ((yi yang) OR (dan yang)) ((jin wong) OR (john wong)) sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan han run ((yi yang) or (dan yang)) ((jin wong) OR (john wong)) sau ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yan han run ((yi yang) or (dan yang)) ((jin wong) OR (john wong)) sau ;*.
