Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
wang wing » wang jing, wang ning, wang liang
wing sun » liang sun, cong sun, nina sun
can take » can make, land take
wong yue » wang yue
oil can » oil cake, oil chad, oil coal
take li » take all, take aim

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 wing sun oil can take li ((shang hai) OR (((hong yu) OR (wong yue)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wing sun oil can take li ((shang hai) or (((hong yu) OR (wong yue)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wing sun oil can take li ((shang hai) or (((hong yu) OR (wong yue)))) ;*.
