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 tai, hanh van
nang xa » nang x, lang xa, mang xa
hanh va » hang va, hanh vi
nang ma » tang ma, sang ma, nang cao
cac loc » cac lop, cac toc, cac hoc
vu san » va san, vu ban
loc va » hoc va, luc va
san ky » sang ky, van ky, dan 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 ((nang xa) OR (nang ma)) hoi. hieu viec cac loc va ((hanh vai) or (hanh va)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky ((nang xa) OR (nang ma)) hoi. hieu viec cac loc va ((hanh vai) OR (hanh va)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky ((nang xa) OR (nang ma)) hoi. hieu viec cac loc va ((hanh vai) or (hanh va)) cua te*".
