Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
hanh vai » hanh vi, hanh va, hanh tai
va hanh » van hanh, va thanh, va danh
sang ky » sang kyo, dang ky, tang ky
nang xa » nang x, lang xa, nang ma
cac luc » cau luc, coc luc, cac nuoc
luc va » duc va, tuc va, loc va
san ky » van ky, dan ky, ban 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 (sang ky)) nang xa hoi. hieu viec cac luc va hanh vai ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((san ky) OR (sang ky)) nang xa hoi. hieu viec cac luc va hanh vai ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((san ky) OR (sang ky)) nang xa hoi. hieu viec cac luc va hanh vai ((cua te) or (cua tu))*".
