Perhaps you should try some spelling variations:
wang ying » wang jing, wang ning, wang liang
wang yang » wang yan, wang liang, wang yanling
wang yong » wang hyoung, wang yan, wang shiyong
song sing » song bing, song ming, song seng
sing long » using long, sing kong, qing long
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui
li song » li cong, li rong, kim song
long do » long d, long du, longer 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 yang))) OR (wang yong)) ((yang li) OR (yang xi)) li song sing long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang ying) OR (wang yang))) or (wang yong)) ((yang li) or (yang xi)) li song sing long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang ying) OR (wang yang))) or (wang yong)) ((yang li) or (yang xi)) li song sing long do ;*.
