Perhaps you should try some spelling variations:
says chuan » say chuan, say chan
chuan daun » chuan dato
zhong zhi » zhang zhi, hong ghi, zhong tai
dong nao » dong cao, dong nan, dong xiao
nao says » who says
yang min » yang mind, yang jin, yang lin
tang min » chang min, sang minh, yang mind

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 nao says chuan daun ((yang min) OR (tang min)) zhong zhi ;~.
• Adding a wildcard symbol may retrieve word variants: dong nao says chuan daun ((yang min) or (tang min)) zhong zhi ;*.
