Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
van trinh » van thinh, van tinh, dan trinh
viec cac » vien cac, viec cua, viec lam
va trinh » va tinh, lap trinh, qua trinh
cac xuc » cam xuc, cac nuoc, chat xuc
cua tre » cua te, cuu tre, cua triet
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
sac ky » cac ky, sai ky
vi cua » vai cua, di cua
tu sac » tu sach, tu cac, tu san

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