Perhaps you should try some spelling variations:
done using » line using, move using
gene yang » gene bank
hua gene » human gene, a gene, hua ren
yang tan » yang fan, yang dean, yang yang
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
dong » doing, long, pong

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: ((dong sin) OR (done using)) ya hua gene yang tan ((hong ghi) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (done using)) ya hua gene yang tan ((hong ghi) OR (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (done using)) ya hua gene yang tan ((hong ghi) OR (hong hai)) ;*.
