Perhaps you should try some spelling variations:
yang fan » zhang fan, yang yang, yang jun
than bau » than bad, than a, than you
can data » can tata, dan data, fan data
yang jin » yang jie, yang jun, ying jin
jin hong » tin hong, jin song, min hong
hong hai » shang hai, zhong tai, dang hai
dean » dewan, jean, den

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: dong ((yang fan) OR (yang dean)) ((than bau) OR (can data)) yang jin hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang fan) OR (yang dean)) ((than bau) or (can data)) yang jin hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((yang fan) OR (yang dean)) ((than bau) or (can data)) yang jin hong hai ;*.
