Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
te sach » toc sach
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
cac tuc » cac toc, cac tu, cac tac
va hanh » van hanh, va thanh, va danh
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
tuc va » thuc va, truc va, tuc xa
vi cua » vai cua, di cua

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 y nang ((xa hoi) OR (mai hoi)). hieu ve cac tuc va hanh vi cua triet~.
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((xa hoi) or (mai hoi)). hieu ve cac tuc va hanh vi cua triet*.
