Perhaps you should try some spelling variations:
wang bingnan » wang binglin, wang shengnan
wang xinyan » wang xiuyan
zhang dai » zhang fan, zhang wei, zhang yan
sheng guo » shen guo, shen zuo, sheng wu
sheng huo » shen guo, shen zuo, sheng wu
kai wong » kai hong, kai fang, kie wong
wong sau » wong sam, wong siu, wong shiu

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 xinyan) OR (wang bingnan)) zhang dai ((sheng guo) OR (sheng huo)) kai wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xinyan) or (wang bingnan)) zhang dai ((sheng guo) OR (sheng huo)) kai wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xinyan) or (wang bingnan)) zhang dai ((sheng guo) OR (sheng huo)) kai wong sau ;*.
