chang kai » shang kai, chang ha, chang mae
wong shiu » cong shu, song shin, wong sau

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang yao) or (wang qian))) or (wang yan)) yang yi chen chang kai ((wong shiu) OR (wong siu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yao) OR (wang qian))) OR (wang yan)) yang yi chen chang kai ((wong shiu) OR (wong siu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yao) or (wang qian))) or (wang yan)) yang yi chen chang kai ((wong shiu) OR (wong siu)) ;*".
