Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
hanh vai » hanh vi, hanh va, hanh tai
viec lam » viec va
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
nang xa » lang xa, nang ma, mang xa
lam luc » lao luc, lam duoc
luc va » duc va, tuc va, loc va
san ky » sang ky, van ky, ban ky
dan ky » van ky
cua tu » cua tuc, cua su, cua cu

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) or (nang x)) hoi. hieu viec lam luc va hanh vai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((san ky) OR (dan ky)) ((nang xa) OR (nang x)) hoi. hieu viec lam luc va hanh vai cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((san ky) OR (dan ky)) ((nang xa) or (nang x)) hoi. hieu viec lam luc va hanh vai cua tu*".
