Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
toc sach » hoc sach, doc sach, thuoc sach
nang xa » nang x, lang xa, nang ma
qua cac » cua cac
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, xuc ban
anh ve » hanh ve, anh va, thanh ve

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