Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
fang yuan » wang yuhan, wang yan, meng yuan
dang haji » dang hai, dato haji
yan yuan » nan yan, yan clan, yan kun
yan guan » gan guan, yang guang, yihan guan
dan yang » daun yang, tan yang, wang yang
yang jui » yang judy, yang di, yang xi
kang hay » eang hay, kang han, dang hai

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