Perhaps you should try some spelling variations:
vu sach » vu bach, su sach, vu khach
sach ly » sach y, sach lo, sach ty
ly nang » ky nang, ly hang, ly vang
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
doi cua » dai cua, hoi cua
cua tre » cua te, cuu tre, cua triet
a dung » ap dung, va dung, am dung
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: vu sach ly nang x hoi. ((hieu ve) OR (lieu va)) cam tuc ((a dung) OR (xay dung)) doi cua tre~.
• Adding a wildcard symbol may retrieve word variants: vu sach ly nang x hoi. ((hieu ve) or (lieu va)) cam tuc ((a dung) or (xay dung)) doi cua tre*.
