min jeong » kin keong, mun leong
min hong » amin hong, min hyoung, kia hong
tin hong » tan hong, kia hong, thi hong
yan yan » yan yuan, nan yan, yang yang
yi chen » jui chen
yan yi » yang yi, tan yi, yan zi
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) yan yan yi chen chang ((min jeong) OR (((min hong) OR (tin hong)))) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wan) yan yan yi chen chang ((min jeong) or (((min hong) or (tin hong)))) shu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wan) yan yan yi chen chang ((min jeong) or (((min hong) or (tin hong)))) shu ;*.
