Perhaps you should try some spelling variations:
wang manning » wang yanling, wang yangming, wang ning
wang danning » wang yanling, wang daoping, wang yangming
yu yang » du yang, yu fang, yu gang
yi yang » yin yang, yi gang, ying yang
how hai » how has, how ai, how have
how hci » how heis
tony a » tony h, tony j

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 manning) OR (wang danning)) tony a ((yu yang) OR (yi yang)) jin ((how hai) OR (how hci)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang manning) or (wang danning)) tony a ((yu yang) OR (yi yang)) jin ((how hai) or (how hci)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang manning) or (wang danning)) tony a ((yu yang) OR (yi yang)) jin ((how hai) or (how hci)) ;*.
