Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan
yang liang » wang liang, yan liang, yang yang
min hyoung » min hong, mun young
wang yang » wang yan, wang liang, wang yanling
hyoung yu » hyoung gun, kyoung yun, hong yu
sin ying » jin ying, li ying, fan ying
ying min » ying jin, kyung min, yang mind

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 ((wang yang) OR (((yang guang) OR (yang liang)))) hui sin ying min hyoung yu ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((wang yang) or (((yang guang) or (yang liang)))) hui sin ying min hyoung yu ;*.
