tang chun » wang chun, tung chung, kang chen
hua gene » human gene, a gene, hua ren

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) OR (wang yan)) y hua gene tang chun leong mi ;~.
• Adding a wildcard symbol may retrieve word variants: ((dong yang) or (wang yan)) y hua gene tang chun leong mi ;*.
