dong bin » dong di, dann bin
hua gene » a gene, hua ren, hy5 gene
chang ma » chang ha, change may, chang min

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong bin) or (dong sin)) ya ((hua gene) OR (human gene)) ((chang ma) or (chang mae)) hong g ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong bin) OR (dong sin)) ya ((hua gene) OR (human gene)) ((chang ma) OR (chang mae)) hong g ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong bin) or (dong sin)) ya ((hua gene) OR (human gene)) ((chang ma) or (chang mae)) hong g ;*".
