Perhaps you should try some spelling variations:
xiaoping tan » xiaoyang tang, xiaoping _, xiaoping how
xiaojing a » xiaoping _, xiaojing part
chia tan » chia lan, chen tan, chia wen
tan yang » dan yang, tan ying, tan yong
yang fan » zhang fan, yang dean, yang yang
fan data » can data, dan data, loan data
deng » den, eng, dung

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: deng ((xiaoping tan) OR (xiaojing a)) chia tan yang fan data (hai OR hari) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "deng ((xiaoping tan) OR (xiaojing a)) chia tan yang fan data (hai or hari) ;~".
• Adding a wildcard symbol may retrieve word variants: deng ((xiaoping tan) OR (xiaojing a)) chia tan yang fan data (hai or hari) ;*.
