zhang shut » zhang shuo, zhang hui
zhong shu » zhang shuo, cong shu, zhong zhi
yan yang » yang yang, yao yang, dan yang
yang yi » yang di, yang xi, yang jui

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 wing) yan yang yi ((chen chang) OR (chin chang)) you ((zhong shu) OR (zhang shut)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) yan yang yi ((chen chang) OR (chin chang)) you ((zhong shu) or (zhang shut)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) yan yang yi ((chen chang) OR (chin chang)) you ((zhong shu) or (zhang shut)) ;*.
