Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
wang yang » wang yan, wang liang, wang yanling
dong bin » dong sin, dann bin
yang thi » dang thi, yang chik, yang di
hong hai » zhong tai, dang hai, hong tan
dong di » dong sin
ya a » a a, y a, ye a
test » text, west, best

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) OR (((dong bin) OR (dong di)))) ya a test yang thi ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (((dong bin) or (dong di)))) ya a test yang thi ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (((dong bin) or (dong di)))) ya a test yang thi ((hong hai) OR (shang hai)) ;*.
