Perhaps you should try some spelling variations:
than wang » chen wang, qian wang, than war
wang ying » wang yang, wang yong, wang jing
yang yao » yang yang, wang yan, yang yi
ying jin » yang jin, jing ji, yang jie
hong hai » shang hai, zhong tai, dang hai
chang ha » chang mae
yang ka » yang fan

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: yang ((yang ka) OR (yang yao)) than wang ying jin ((hong hai) OR (chang ha)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((yang ka) OR (yang yao)) than wang ying jin ((hong hai) or (chang ha)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang ((yang ka) OR (yang yao)) than wang ying jin ((hong hai) or (chang ha)) ;*.
