Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
sing kong » king kong, hong kong
kim song » kim young, kim eung
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui
li song » li cong, jie song, jin song
li rong » yi rong, li cong, shi rong
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 ((yang li) OR (yang xi)) ((((li song) OR (li rong))) OR (kim song)) sing kong do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((yang li) or (yang xi)) ((((li song) OR (li rong))) or (kim song)) sing kong do ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying ((yang li) or (yang xi)) ((((li song) OR (li rong))) or (kim song)) sing kong do ;*.
