Perhaps you should try some spelling variations:
chuan kao » chuan dato, chuan fa
tin shang » tin hong, bin zhang, jin chang
shang hai » shang kai, dang hai, chang ha
yang fan » zhang fan, yang yang, yang jin
hua xiao » hu xiao, huang xiao, wu xiao
yang tin » yang jin, yang lin, yang jing
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: wang ((yang fan) OR (yang dean)) ((chuan kao) OR (hua xiao)) yang tin shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang fan) OR (yang dean)) ((chuan kao) or (hua xiao)) yang tin shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang fan) OR (yang dean)) ((chuan kao) or (hua xiao)) yang tin shang hai ;*.
