Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
jian sang » jia fang
sang minh » kang minah, anh minh, song min
shang hai » shang kai, dang hai, chang ha
chang mae » chang ha, changes made
shi jian » shi japan, shi lin, shi dan
yang ka » yang fan, yang yao

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 shi jian sang minh ((shang hai) OR (chang mae)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang ka shi jian sang minh ((shang hai) or (chang mae)) ;*.
