Perhaps you should try some spelling variations:
hyoung kim » hyung kim, yong kim, hyoung il
human gene » human genome, human gender, human bone
yang chik » nong chik, wang chi
hua gene » a gene, hua ren, hy5 gene
yang shi » yang di, yang jui, yang xi
dan hai » dang hai, dan phan, dann hat
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 hyoung kim ((hua gene) OR (human gene)) ((yang shi) OR (yang chik)) dan hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung kim ((hua gene) or (human gene)) ((yang shi) OR (yang chik)) dan hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang hyoung kim ((hua gene) or (human gene)) ((yang shi) OR (yang chik)) dan hai ;*.
