Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
hieu van » hieu va, thien van, lieu va
su triet » su viet, su tien, ve triet
su sach » so sach, vu sach
van hoe » van hoc, van hieu, van hien
nam xuc » cam xuc, nam xua, nam thuc
va hanh » van hanh, va thanh, va danh
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang ((van hoa) or (van hoe)). hieu van nam xuc va hanh vi ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang ((van hoa) OR (van hoe)). hieu van nam xuc va hanh vi ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ((van hoa) or (van hoe)). hieu van nam xuc va hanh vi ((cua triet) OR (su triet))*".
