Perhaps you should try some spelling variations:
hyoung gun » young eun
yuan kang » yuan wang, yuan chang, chan kang
yan liang » yang liang, wang liang, you liang
qian wang » yiqian wang, qian rong, qian yan
yan hyun » yan yuan, yang yun
yan hua » tan hua, ya hua, wang hua
hua ren » hua chen
yan kun » yan guan, yan yuan

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: ((yuan kang) OR (((yan liang) OR (qian wang)))) yan hua ren ((yan hyun) OR (yan kun)) hyoung gun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) or (((yan liang) or (qian wang)))) yan hua ren ((yan hyun) OR (yan kun)) hyoung gun ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) or (((yan liang) or (qian wang)))) yan hua ren ((yan hyun) OR (yan kun)) hyoung gun ;*.
