Perhaps you should try some spelling variations:
china chang » chin chang, china zhang, china changqi
chang yulu » chen yulu, chang you, chang yun
yulu chen » yu chen
shang hai » shang kai, dang hai, chang ha
yang jui » yang judy, yang di
yang jin » yang jie, yang jun, ying jin
yang xi » yang di
yang yi » yang di

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: can china chang yulu chen ((((yang jui) OR (yang jin))) OR (((yang xi) OR (yang yi)))) shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: can china chang yulu chen ((((yang jui) or (yang jin))) or (((yang xi) or (yang yi)))) shang hai ;*.
