Perhaps you should try some spelling variations:
wan hyoung » wang hyoung, man houng, min hyoung
yang hoong » wang hong
yan liang » yang liang, wang liang, you liang
qian june » qian jun, plan june
hoong ang » hoong chang, soon ang
yan yuan » yan guan, fang yuan, nan yan
ang hai » dang hai, shang hai, eang hay

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: wan hyoung ((((yan liang) OR (yan yuan))) OR (qian june)) du yang hoong ang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wan hyoung ((((yan liang) or (yan yuan))) or (qian june)) du yang hoong ang hai ;*.
