Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
hanh vai » hanh vi, hanh va, hanh tai
cac nuoc » cap nuoc, hoc nuoc, dat nuoc
cac luc » cau luc, coc luc, cac cuoc
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
nang xa » nang x, lang xa, nang ma
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.

• Performing a fuzzy search may retrieve terms with similar spellings: vu ((san ky) or (dan ky)) nang xa hoi. hieu viec ((cac luc) OR (cac nuoc)) va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((san ky) OR (dan ky)) nang xa hoi. hieu viec ((cac luc) OR (cac nuoc)) va hanh vai 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 ((cac luc) OR (cac nuoc)) va hanh vai cua te*".
