Perhaps you should try some spelling variations:
vay doanh » ly doanh, voi doanh, von doanh
thien van » thi van
van doanh » toan doanh, van dong, van thanh
hieu van » hieu va, lieu va, hieu ve
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
cac toc » cac toi, cac nuoc, cac thoi
dao cua » dai cua, day cua, dan cua
te cac » tu cac, ve cac, te cao
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 cac ky lang xa hoi. ((hieu van) OR (thien van)) cac toc ((vay doanh) OR (van doanh)) dao cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky lang xa hoi. ((hieu van) or (thien van)) cac toc ((vay doanh) OR (van doanh)) dao cua te~".
• Adding a wildcard symbol may retrieve word variants: te cac ky lang xa hoi. ((hieu van) or (thien van)) cac toc ((vay doanh) OR (van doanh)) dao cua te*.
