Perhaps you should try some spelling variations:
hyoung yan » kyoung yang, hyoung gun, kyoung yun
gain yang » dan yang, daun yang, tan yang
kong hang » kong heng, kong hong, kong land
yun gain » run gain, you gain, n gain
eang hay » dang hai, kang han
yan yun » yan yuan, yang yun, yan kun
yang yi » yang di, yang xi, yang jui
wang » wan, lang

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 OR wing) hyoung yan yun gain yang yi ((eang hay) OR (kong hang)) ;~.
• Adding a wildcard symbol may retrieve word variants: (wang or wing) hyoung yan yun gain yang yi ((eang hay) or (kong hang)) ;*.
