Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
sach ky » sac ky, sach y, sach kem
sach ty » sach y, sach tu, sach thu
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, vuc van
ve cac » va cac, vien cac
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, 5 hoi

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: thu ((sach ky) OR (sach ty)) nang ((x hoi) OR (x ho)). hieu ve cac xuc van hanh vi cua triet~.
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) or (sach ty)) nang ((x hoi) or (x ho)). hieu ve cac xuc van hanh vi cua triet*.
