Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
l changed » _ changed, 19 changed, il changer
a changed » _ changed, a change, has changed
shang hai » shang kai, dang hai, chang ha
dan yang » daun yang, tan yang, wang yang
wong yue » wang yue, hong yu
judy » july

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: dan yang yang judy ((l changed) OR (a changed)) world ((shang hai) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dan yang yang judy ((l changed) OR (a changed)) world ((shang hai) or (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: dan yang yang judy ((l changed) OR (a changed)) world ((shang hai) or (wong yue)) ;*.
