Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
han zhang » han chang, hao zhang, yan zhang
zhang won » chang won, zhang hong, zhang rong
zhong zhi » hong ghi, zhong tai
zhang zhi » wang zhi, zhang wei, zhang dai
yang xi » yang di, yang yi, yang jui
hong yu » wong yue
xi han » ti han, xi zhang
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) yang yang xi han zhang won ((((zhong zhi) OR (zhang zhi))) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yang yang xi han zhang won ((((zhong zhi) OR (zhang zhi))) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yang yang xi han zhang won ((((zhong zhi) OR (zhang zhi))) or (hong yu)) ;*.
