Perhaps you should try some spelling variations:
human gene » human genome, human gender, human bone
gene tang » gene bank
yang yao » yang yang, wang yan, yang yi
yang jui » yang judy, yang xi, yang yi
min gong » min hong, minh cong, amin hong
3 human » 2 human
ng 3 » ngs 3, nr 3, n 3

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: ((((yang yao) OR (yang jui))) OR (yang di))ng 3 human gene tang ((min gong) OR (xian gong)) gang ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yao) or (yang jui))) or (yang di))ng 3 human gene tang ((min gong) OR (xian gong)) gang ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang yao) or (yang jui))) or (yang di))ng 3 human gene tang ((min gong) OR (xian gong)) gang ;*.
