Perhaps you should try some spelling variations:
wang ying » wang yang, wang ning, wang liang
wang yong » wang yang, wang hyoung, wang yan
wang jing » wang ning, wang liang, wang yang
song ming » song bing, gong min, jong min
song min » gong min, jong min, song jin
gong hui » tong hui, tong shui, wang hui
di li » li li

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 ying) OR (wang yong))) OR (wang jing)) yang di li ((song ming) OR (song min)) gong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang ying) or (wang yong))) or (wang jing)) yang di li ((song ming) OR (song min)) gong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang ying) or (wang yong))) or (wang jing)) yang di li ((song ming) OR (song min)) gong hui ;*.
