Perhaps you should try some spelling variations:
nhieu viec » nhien viet
hieu viec » hieu ve, sieu viet, hieu hien
van hanh » van thanh, ban hanh, van anh
nang ma » tang ma, sang ma, nang cao
va hanh » va thanh, va danh, ban hanh
vai cua » dai cua, hai cua, lai cua
vu van » tu van
ma hoi » mai hoi, xa hoi, ma hoa
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: vu van ky nang ma hoi. ((hieu viec) OR (nhieu viec)) coc luc ((va hanh) OR (van hanh)) vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu van ky nang ma hoi. ((hieu viec) OR (nhieu viec)) coc luc ((va hanh) or (van hanh)) vai cua te~".
• Adding a wildcard symbol may retrieve word variants: vu van ky nang ma hoi. ((hieu viec) OR (nhieu viec)) coc luc ((va hanh) or (van hanh)) vai cua te*.
