Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
cac xuc » cam xuc, cac nuoc, chat xuc
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
va hanh » van hanh, va thanh, va danh
xuc va » duc va, tuc va, luc va
vu san » va san, vu ban
san ky » sang ky, van ky, dan 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 ((nang xa) or (nang ma)) hoi. hieu viec cac xuc va hanh vi ((cua te) OR (cua tu))~.
• 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 xuc va hanh vi ((cua te) OR (cua tu))*.
• 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 xuc va hanh vi ((cua te) OR (cua tu))*".
