gene one » gene clone, gene gene, gene we
kong siu » kong eiu, dong sin, kong sar
wong siu » wong shiu, wong sau, wong siew
one nan » one non, one bank
yang i » yang di, yang xi, yang yi
i gene » _ gene, a gene, e gene

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: ((yan wang) OR (yuan chang)) yang i gene one nan ((kong siu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (yuan chang)) yang i gene one nan ((kong siu) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (yuan chang)) yang i gene one nan ((kong siu) OR (wong siu)) ;*.
