yang yang » wang yang, wang yan
dang hari » dang hai
yan guan » gan guan, yan yuan, yihan guan
tan yong » tan hong, tan kong, tan yang
yong duc » tung duc, long du, yong c

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: wing hyoung ((((yan guan) OR (yang guang))) OR (yang yang)) tan yong duc dang hari ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing hyoung ((((yan guan) OR (yang guang))) or (yang yang)) tan yong duc dang hari ;*".
