Perhaps you should try some spelling variations:
hyoung yan » kyoung yang, hyoung gun, kyoung yun
daun yang » du yang, tan yang, un yang
dan yang » tan yang, wang yang, yang yang
gang hai » dang hai, shang hai, eang hay
yan yun » yan yuan, yang yun, yan kun
xi gang » ii gang, i gang, li gang
wang » wing, 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 hyoung yan yun ((dan yang) OR (daun yang)) xi gang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung yan yun ((dan yang) or (daun yang)) xi gang hai ;*.
