Perhaps you should try some spelling variations:
yong yang » dong yang, ying yang, kyoung yang
yang yang » wang yang, wang yan
zhong zhi » zhang zhi, hong ghi, zhong tai
xi wang » x wang, li wang, xi kang
wang li » wang lei, wang lin, tang li
hong yu » wong yue
li yi » lin yi, li li, lu yi

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 ((yong yang) OR (yang yang)) xi wang li yi ((zhong zhi) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) OR (yang yang)) xi wang li yi ((zhong zhi) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yang) OR (yang yang)) xi wang li yi ((zhong zhi) or (hong yu)) ;*.
