Perhaps you should try some spelling variations:
wang liang » wang yang
liang yang » liang ying, wang yang, yang yang
min hyoung » min hong, mun young
hyoung hui » hyoung gun
yang tai » yang dali, yang di, yang jui
yi song » yi rong, kim song, jie song
li song » li cong, li rong, kim song

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 liang yang tai ((yi song) OR (li song)) min hyoung hui ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang yang tai ((yi song) or (li song)) min hyoung hui ;*.
