Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
tang van » dang van, hoang van, trong van
thuc can » thuc chan, thuc dan, thuc van
dan thuc » dan toc, am thuc
viec dan » viec dang, viec ban, viec dat
te sach » toc sach
can dan » canh dan, cac dan, can ban
sach tu » sach thu, cach tu, sach ty
tang ma » mang may
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
dan va » doan va, dan ca, ban va
va cua » va chua, via cua, ca cua

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 tu ((nang xa) OR (((tang ma) OR (tang van)))) hoi. nhieu viec dan thuc can dan va cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu ((nang xa) or (((tang ma) OR (tang van)))) hoi. nhieu viec dan thuc can dan va cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach tu ((nang xa) or (((tang ma) OR (tang van)))) hoi. nhieu viec dan thuc can dan va cua tre*.
