Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
sach vu » sach va, sach tu, sach uu
vu nang » vuc nang, va nang, vu dang
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 » luc va, xac va
tuc va » thuc va, truc va, tuc xa
di cua » dai cua, doi cua, de cua
x hoi » xa hoi, o hoi, x ho

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: toc sach vu nang x hoi. hieu ve cam ((((xuc va) OR (tuc va))) OR (duc va)) hanh di cua tre~.
• Adding a wildcard symbol may retrieve word variants: toc sach vu nang x hoi. hieu ve cam ((((xuc va) or (tuc va))) or (duc va)) hanh di cua tre*.
