Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yong gang » gong gang, hong gang, yong phang
wang ning » wang jing, wang liang, wang yang
yan yuan » fang yuan, yan clan, yan kun
yan guan » gan guan, yang guang, yihan guan
eang hay » dang hai, kang han
nan yan » nan ya, wang yan, qian yan

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 gang ((((yan yuan) OR (nan yan))) OR (yan guan)) wang ning eang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong gang ((((yan yuan) OR (nan yan))) or (yan guan)) wang ning eang hay ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong gang ((((yan yuan) OR (nan yan))) or (yan guan)) wang ning eang hay ;*.
