Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang jing
ming long » ming kong, making long, going long
qing long » going long, using long
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
li song » li rong, kim song, jie song
li cong » li rong, jiu cong

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 jin) OR (yang jun)) ((li song) OR (li cong)) ((ming long) OR (qing long)) du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((yang jin) OR (yang jun)) ((li song) or (li cong)) ((ming long) or (qing long)) du ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying ((yang jin) OR (yang jun)) ((li song) or (li cong)) ((ming long) or (qing long)) du ;*.
