Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
sang minh » kang minah, anh minh, song min
shang hai » shang kai, dang hai, hong hai
dan sang » dan yang, dan dana, dan qing
chang ha » chang mae
shi dan » shi fan, shi ding, shi jian
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: yang yang dean shi dan sang minh ((shang hai) OR (chang ha)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang dean shi dan sang minh ((shang hai) or (chang ha)) ;*.
