Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
nang van » dang van, tang van, lang van
hieu van » hieu va, thien van, lieu va
va hanh » van hanh, va thanh, va danh
hanh di » hanh vi, hanh de, hang di
su sach » so sach, vu sach
nam xuc » cam xuc, nam xua, nam thuc
van hoi » van hoa, van hoc, van hoe
y nang » ky nang, ly nang, v nang

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 hoi. hieu van ((nam xuc) or (am thuc)) va hanh di ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang van hoi. hieu van ((nam xuc) OR (am thuc)) va hanh di ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang van hoi. hieu van ((nam xuc) or (am thuc)) va hanh di ((cua triet) OR (su triet))*".
