ka chuan » say chuan, hai chuan, ka chai
yang jin » yang jie, yang jun, ying jin

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: dong yang ((ka hua) OR (ka chuan)) gene yang jin ((hong shu) OR (wong shiu)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang ((ka hua) OR (ka chuan)) gene yang jin ((hong shu) or (wong shiu)) ;".
• Adding a wildcard symbol may retrieve word variants: dong yang ((ka hua) OR (ka chuan)) gene yang jin ((hong shu) or (wong shiu)) ;*.
