Perhaps you should try some spelling variations:
te cach » ve cach, tu cach, te cac
hanh di » hanh de, hang di, danh di
xuc van » duc van, luc van, vuc van
hieu va » lieu va, hieu qua
tu nang » tru nang, tu nong, tu nano
te sach » toc sach
cua tre » cua te, cuu tre, cua triet
va cam » va cham, va cac, va cao
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: ((te cach) OR (te sach)) tu nang x hoi. hieu va cam xuc van ((hanh di) OR (hanh vi)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cach) OR (te sach)) tu nang x hoi. hieu va cam xuc van ((hanh di) or (hanh vi)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te cach) OR (te sach)) tu nang x hoi. hieu va cam xuc van ((hanh di) or (hanh vi)) cua tre*.
