Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec lam » viec va
van hanh » van thanh, ban hanh, van anh
va hanh » va thanh, va danh, ban hanh
lai cua » dai cua, hai cua, lai chau
nang xa » nang x, lang xa, nang ma
lam luc » lao luc, lam duoc
san ky » sang ky, van ky, ban ky
dan ky » van ky
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 ((san ky) OR (dan ky)) nang xa hoi. hieu viec lam luc ((va hanh) OR (van hanh)) lai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((san ky) or (dan ky)) nang xa hoi. hieu viec lam luc ((va hanh) OR (van hanh)) lai cua te~".
• Adding a wildcard symbol may retrieve word variants: vu ((san ky) or (dan ky)) nang xa hoi. hieu viec lam luc ((va hanh) OR (van hanh)) lai cua te*.
