Perhaps you should try some spelling variations:
gene bank » gene banks, one bank, genomen bank
bank aid » band aid, bank card, bank adb
aid than » said than, aid can, aid has
dong di » dong sin
than we » than one
set a » set _
get a » get _
et a » et al, et la, e a
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) OR (dong di)) ((((set a) OR (get a))) OR (et a)) gene bank aid than we ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) OR (dong di)) ((((set a) OR (get a))) OR (et a)) gene bank aid than we ;*.
