yang yao » yang yang, wang yan, yang yi
hua gene » human gene, hua ren, hy5 gene
yang jun » yang jui, pang jun, yang jin
ying jin » yang jin, jing ji, yang jie

a gene » a genre, a gender, a gentle

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: dong ((yang ka) OR (yang yao)) ((hua gene) or (a gene)) ((yang jun) or (ying jin)) wong shiu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang ka) OR (yang yao)) ((hua gene) OR (a gene)) ((yang jun) OR (ying jin)) wong shiu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang ka) OR (yang yao)) ((hua gene) or (a gene)) ((yang jun) or (ying jin)) wong shiu ;*".
