Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
dang xay » dang van, van xay
viec cam » viec lam, viec cua, viec va
lang van » dang van, tang van, hoang van
tu sach » thu sach, su sach, te sach
tinh de » tinh da, sinh de, tinh he
va tinh » may tinh
sach ky » sac ky, sach y, sach ty
lang xa » lang ha
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va
de cua » le cua, te cua, dieu cua

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 ((((lang xa) OR (lang van))) OR (dang xay)) hoi. nhieu viec cam xuc va tinh de cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((((lang xa) OR (lang van))) or (dang xay)) hoi. nhieu viec cam xuc va tinh de cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((((lang xa) OR (lang van))) or (dang xay)) hoi. nhieu viec cam xuc va tinh de cua tre*.
