Perhaps you should try some spelling variations:
wang ying » wang yang, wang jing, wang liang
wang ning » wang jing, wang liang, wang yang
wang yong » wang yang, wang hyoung, wang yan
song sing » song bing, song ming, song seng
sing kong » king kong, hong kong
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui
li song » li cong, li rong, kim song
kong do » long do

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 ning))) OR (wang yong)) ((yang li) OR (yang xi)) li song sing kong do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang ying) OR (wang ning))) or (wang yong)) ((yang li) or (yang xi)) li song sing kong do ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang ying) OR (wang ning))) or (wang yong)) ((yang li) or (yang xi)) li song sing kong do ;*.
