gain yang » dan yang, daun yang, tan yang
zhang hay » zhang han, zhang fan, zhang yan
xi zhang » li zhang, xiao zhang, bin zhang
yan yun » yan yuan, yang yun, yap yun
yan kun » yan guan, yan yuan
yang xi » yang di, yang yi, 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 yong) OR (wang yan)) ((yan yun) OR (yan kun)) gain yang xi zhang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (wang yan)) ((yan yun) OR (yan kun)) gain yang xi zhang hay ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (wang yan)) ((yan yun) OR (yan kun)) gain yang xi zhang hay ;*.
