Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh lai » hanh lam, thanh lap, thanh loi
hanh tai » thanh tai, hang tai, han tai
toc sach » hoc sach, doc sach, thuoc sach
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, vuc van
sach tu » sach thu, cach tu, sach ty
nang xa » nang x, lang xa, nang ma
tu nang » tru nang, tu nong, tu nano
cua te » cua tu

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: toc sach tu nang xa hoi. hieu va cac xuc van ((hanh lai) OR (hanh tai)) ((cua te) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach tu nang xa hoi. hieu va cac xuc van ((hanh lai) OR (hanh tai)) ((cua te) or (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: toc sach tu nang xa hoi. hieu va cac xuc van ((hanh lai) OR (hanh tai)) ((cua te) or (cua triet))*.
