Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
hieu va » lieu va, hieu qua
cam tuc » cam tu, nam thuc, dam thuc
hanh di » hanh vi, hanh de, hang di
cua tre » cua te, cuu tre, cua triet
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 ty xang xa hoi. hieu va ((cam tuc) OR (cam xuc)) van hanh di cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach ty xang xa hoi. hieu va ((cam tuc) or (cam xuc)) van hanh di cua tre*.
