Perhaps you should try some spelling variations:
te sach » toc sach
sach tu » sach thu, cach tu, sach ty
hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
cua tre » cua te, cuu tre, cua triet
cam tuc » cam tu, nam thuc, dam thuc
hieu va » lieu va, hieu qua
xang xa » lang xa, mang xa, ang xa
tu xang » ty xang, tu lang, tu quang

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 tu xang xa hoi. hieu va ((cam tuc) OR (cam xuc)) van ((hanh di) OR (hanh de)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu xang xa hoi. hieu va ((cam tuc) or (cam xuc)) van ((hanh di) OR (hanh de)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach tu xang xa hoi. hieu va ((cam tuc) or (cam xuc)) van ((hanh di) OR (hanh de)) cua tre*.
