Perhaps you should try some spelling variations:
hieu nghe » lieu nghe, hiem ngheo, nhiem nghe
van hanh » van thanh, ban hanh, van anh
thuc van » thuc vat, thuc dan, thuc va
nam thuc » nam thuoc, am thuc, nam thu
lang van » dang van, tang van, hoang van
nghe nam » nghe lam, nghiep nam, nghe nano
te sach » toc sach
lang xa » lang ha, dang xay
cua tuc » cua duc, cua thuoc, luat tuc
cua tu » cua su, cua cu, cua te

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: te sach y ((lang xa) OR (lang van)) hoi. hieu nghe nam thuc van hanh vi ((cua tu) OR (cua tuc))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang xa) OR (lang van)) hoi. hieu nghe nam thuc van hanh vi ((cua tu) or (cua tuc))~".
• Adding a wildcard symbol may retrieve word variants: te sach y ((lang xa) OR (lang van)) hoi. hieu nghe nam thuc van hanh vi ((cua tu) or (cua tuc))*.
