Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
viec cac » vien cac, viec cua, viec lam
trinh vi » trinh va, trinh ve, trinh viet
va trinh » van trinh, va tinh, lap trinh
cua tre » cuu tre, cua triet, dua tren
cac xuc » cam xuc, cac nuoc, chat xuc
sach ky » sac ky, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
xuc va » duc va, tuc va, luc va
cua te » cua tu

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: tu ((sach ky) OR (sach y)) nang xa hoi. nhieu viec cac xuc va trinh vi ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sach y)) nang xa hoi. nhieu viec cac xuc va trinh vi ((cua tre) OR (cua te))~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sach y)) nang xa hoi. nhieu viec cac xuc va trinh vi ((cua tre) OR (cua te))*.
