Perhaps you should try some spelling variations:
yang zhang » yan zhang, zhang zhang, yang yang
fan chuan » say chuan, ka chuan
hai chuan » say chuan, ka chuan, tai chun
tan yang » dan yang, tan ying, tan yong
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai
chang ha » chang mae

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