gan guan » quan guan, fan guon, gui guan
yan guan » yan yuan, yang guang, yihan guan
dan yang » daun yang, tan yang, wang yang
kang hay » eang hay, kang han, kang tae
yang wu » yang du, yang mu, yang jui
hai » hadi, haji, hari

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 ((gan guan) OR (yan guan)) dan yang wu ((kang hay) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((gan guan) OR (yan guan)) dan yang wu ((kang hay) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((gan guan) OR (yan guan)) dan yang wu ((kang hay) or (dang hai)) ;*.
