Perhaps you should try some spelling variations:
zhong zhi » zhang zhi, hong ghi
zhong tai » hong tan, hong hai
tan yang » dan yang, tan ying, tan yong
yao yang » yang yang
iii gene » iii rene, iii gender, iii genome
bank aid » bank card, bank adb, bank a
band aid » brand aid, based aid, band side

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 ((tan yang) OR (yao yang)) iii gene ((bank aid) OR (band aid)) ((zhong zhi) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((tan yang) or (yao yang)) iii gene ((bank aid) or (band aid)) ((zhong zhi) OR (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((tan yang) or (yao yang)) iii gene ((bank aid) or (band aid)) ((zhong zhi) OR (zhong tai)) ;*.
