Perhaps you should try some spelling variations:
vay doanh » van doanh, ly doanh, voi doanh
doanh dao » doanh bao, doanh cao, doanh giao
hieu van » hieu va, thien van, lieu va
cac thoi » cac toi, cac hop, cac tro
cap nuoc » dat nuoc
te sach » toc sach
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
cac toc » cac toi, cac nuoc
dao cua » dai cua, day cua, dan cua
sach ky » sac ky, sach y, sach ty
cua te » cua tu

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 ky lang xa hoi. hieu van ((((cac toc) OR (cac thoi))) OR (cap nuoc)) vay doanh dao cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang xa hoi. hieu van ((((cac toc) OR (cac thoi))) or (cap nuoc)) vay doanh dao cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang xa hoi. hieu van ((((cac toc) OR (cac thoi))) or (cap nuoc)) vay doanh dao cua te*.
