Perhaps you should try some spelling variations:
yang jun » yang jui, pang jun, yang jin
kang kim » kanaga kim, yong kim, kay kim
jeong su » jeong _, jeong mi, jeong 情
yan tan » tan tan, yan clan, yan guan
a1 gene » a gene, 1 gene, l1 gene
11 gene » 1 gene, l1 gene, 11 gender
wang » wing, wan, lang

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 tan ((a1 gene) OR (11 gene)) ((yang jun) OR (((kang kim) OR (tan kim)))) jeong su ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan tan ((a1 gene) OR (11 gene)) ((yang jun) or (((kang kim) or (tan kim)))) jeong su ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan tan ((a1 gene) OR (11 gene)) ((yang jun) or (((kang kim) or (tan kim)))) jeong su ;*.
