Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yong yan » yang yang, dong yang, ying yang
yun gain » run gain, you gain, yun hin
yi dang » yi chang
yi yang » yin yang, yu yang, ying yang
yi gang » ii gang, i gang, li gang
n gain » _ gain, run gain

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang yong yan ((yun gain) or (n gain)) yang ((yi dang) or (((yi yang) OR (yi gang)))) hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong yan ((yun gain) OR (n gain)) yang ((yi dang) OR (((yi yang) OR (yi gang)))) hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yan ((yun gain) or (n gain)) yang ((yi dang) or (((yi yang) OR (yi gang)))) hai ;".
• Adding a wildcard symbol may retrieve word variants: wang yong yan ((yun gain) or (n gain)) yang ((yi dang) or (((yi yang) OR (yi gang)))) hai ;*.
