Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cau triet » cau trieu, su triet, va triet
van hanh » van thanh, ban hanh, van anh
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
sach ty » sach y, sach tu, sach thu
sach ky » sac ky, sach y, sach kem
van cau » van dau, van hau, van chat
cau xuc » cam xuc, cau luc, cau truc
xuc van » duc van, luc van, vuc van

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: tu ((sach ky) OR (sach ty)) nang xa hoi. hieu van cau xuc van hanh vi ((cau triet) OR (cua triet))~.
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sach ty)) nang xa hoi. hieu van cau xuc van hanh vi ((cau triet) or (cua triet))*.
