min jeong » kin keong, mun leong
yan yuan » yan guan, fang yuan, nan yan
min hong » amin hong, tin hong, min hyoung
yuan li » yuan lin, guan li, yuan zi
li chen » yi chen, jui chen
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yuan li chen zheng ((min jeong) OR (min hong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yuan li chen zheng ((min jeong) OR (min hong)) shu ;*.
