Perhaps you should try some spelling variations:
yuan wang » yan wang, yuan kang, yuan chang
zhang wei » zhen wei
well than » well train, well what
wei gene » e gene, i gene, iii gene
well can » well a, all can
wong siu » wong shiu, kong siu, wong sau
tan kai » tan kah, yuan kai

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: ((tan kai) OR (yuan wang)) zhang wei gene ((well than) OR (well can)) wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tan kai) or (yuan wang)) zhang wei gene ((well than) OR (well can)) wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((tan kai) or (yuan wang)) zhang wei gene ((well than) OR (well can)) wong siu ;*.
