Perhaps you should try some spelling variations:
xiaoping than » xiaoping shi
xiaoping how » mapping how, xiaoping _, xiaoping shi
china wen » chia wen, china won, ching wen
zhang dai » zhang wei, zhang yan, zhang lei
wen yang » wei yang, wen wang, chen yang
yang jin » yang jie, yang jun, ying jin

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 ((xiaoping than) OR (xiaoping how)) china wen yang jin ((zhang dai) OR (zhang fan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((xiaoping than) or (xiaoping how)) china wen yang jin ((zhang dai) OR (zhang fan)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((xiaoping than) or (xiaoping how)) china wen yang jin ((zhang dai) OR (zhang fan)) ;*.
