shang hai » shang kai, dang hai, chang ha
wing man » wing tan, wing means, big man
wing ian » wing tan, twinn ian, wing sun
liu yuan » liu jiyuan, liu yu, chu yuan
wang dan » wang yan, wang ban, wang yidan

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: ((wing man) OR (wing ian)) can ((liu yuan) OR (liu yan)) wang dan shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing man) or (wing ian)) can ((liu yuan) OR (liu yan)) wang dan shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing man) or (wing ian)) can ((liu yuan) OR (liu yan)) wang dan shang hai ;*.
