Perhaps you should try some spelling variations:
jeong ghi » hong ghi, jeong mi
yan dang » yan wang, yang yang, yan liang
sang min » sang minh, song min, tang min
lang min » tang min, chang min, lang wien
a1 gene » a gene, 11 gene, l1 gene
1 gene » 11 gene, l1 gene, _ gene
wang » wing, wan

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: wang yan dang ((a1 gene) OR (1 gene)) ((sang min) OR (lang min)) jeong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan dang ((a1 gene) OR (1 gene)) ((sang min) or (lang min)) jeong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan dang ((a1 gene) OR (1 gene)) ((sang min) or (lang min)) jeong ghi ;*.
