hua gene » human gene, a gene, hua ren
tang min » chang min, sang minh, yang mind
yang lin » yang jin, yang li, yang liang
wang lin » wang li, wang qin, wang limin
ying jin » yang jin, jing ji, yang jie
hong shu » cong shu, tong shui, wong shiu
ala » alan, alam, alia

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: long hoang ala hua gene ((tang min) OR (((((yang lin) OR (wang lin))) OR (ying jin)))) hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long hoang ala hua gene ((tang min) or (((((yang lin) OR (wang lin))) or (ying jin)))) hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: long hoang ala hua gene ((tang min) or (((((yang lin) OR (wang lin))) or (ying jin)))) hong shu ;*.
