Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
lang xa » lang ha, dang xay, lang van
cac luc » cau luc, coc luc, cac nuoc
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
san ky » sang ky, dan ky, ban ky
luc va » duc va, tuc va, loc va
vi cua » vai cua, di cua
cua tu » cua tuc, cua su, cua cu

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 (van ky)) lang xa hoi. hieu viec cac luc va danh vi cua tu~.
• Adding a wildcard symbol may retrieve word variants: vu ((san ky) or (van ky)) lang xa hoi. hieu viec cac luc va danh vi cua tu*.
