Perhaps you should try some spelling variations:
hanh de » hanh ve, hanh kem
va hanh » van hanh, va thanh, va danh
cam tuc » cam tu, nam thuc, dam thuc
sach ty » sach y, sach thu, xach tay
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sach tu » sach thu, cach tu, sach uu
de cua » le cua, te cua, dieu 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) OR (sach tu)) nang xa hoi. hieu va ((cam tuc) OR (cam xuc)) va hanh de cua tre~.
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) or (sach tu)) nang xa hoi. hieu va ((cam tuc) or (cam xuc)) va hanh de cua tre*.
