Perhaps you should try some spelling variations:
vuc nang » cuc nang, chuc nang, van nang
te sach » toc sach
vu nang » va nang, vu dang, v nang
hieu ve » hieu va, hieu van
hanh di » hanh vi, hanh de, hang di
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
xuc va » tuc va, luc va, xac va
di cua » dai cua, doi cua, de 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: te sach ((vu nang) OR (vuc nang)) xa hoi. hieu ve cam ((xuc va) OR (duc va)) hanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((vu nang) OR (vuc nang)) xa hoi. hieu ve cam ((xuc va) or (duc va)) hanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((vu nang) OR (vuc nang)) xa hoi. hieu ve cam ((xuc va) or (duc va)) hanh di cua tre*.
