Perhaps you should try some spelling variations:
liang ying » liang liying, huang ying, zhang ying
min hyoung » mun young
yang yang » wang yang, wang yan
yang jie » yang jin, yang di, yang jui
min hong » amin hong, tin hong, min jeong
jing ji » ying jin
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: liang ying ((((jing ji) OR (yang yang))) OR (yang jie)) li song ((min hong) OR (min hyoung)) d ;~.
• Adding a wildcard symbol may retrieve word variants: liang ying ((((jing ji) or (yang yang))) or (yang jie)) li song ((min hong) or (min hyoung)) d ;*.
