Perhaps you should try some spelling variations:
wang daoping » wang xiaoping, wang danning, wang xiaobing
wang ning » wang liang, wang yang, wang yong
wang jing » wang liang, wang yang, wang yong
yang jin » yang jie, yang jun, shang jin
ying jin » jing ji, yang jie
how hai » how has, how ai, how hci
tony a » tony h, tony j
a das » 1 das, 2 das, 3 das

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 ning) OR (wang jing))) OR (wang daoping)) tony a das ((yang jin) OR (ying jin)) how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang ning) or (wang jing))) or (wang daoping)) tony a das ((yang jin) OR (ying jin)) how hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang ning) or (wang jing))) or (wang daoping)) tony a das ((yang jin) OR (ying jin)) how hai ;*.
