Perhaps you should try some spelling variations:
hyoung yan » kyoung yang, hyoung gun, kyoung yun
gain yang » dan yang, daun yang, yin yang
tan yang » dan yang, tan ying, tan yong
yan kun » yan guan, yan yuan
yi dang » yi yang, yi chang
yi 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 kun ((gain yang) OR (tan yang)) ((yi dang) OR (yi gang)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung yan kun ((gain yang) or (tan yang)) ((yi dang) OR (yi gang)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang hyoung yan kun ((gain yang) or (tan yang)) ((yi dang) OR (yi gang)) hai ;*.
