Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ba trung » tai trung, nam trung, do trung
so sach » so sanh, bo sach, co sach
nang ma » tang ma, sang ma, nang cao
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa
vi cua » vai cua, di cua
va ba » va bai, va bao, va ban

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: so sach y nang ma hoi. hieu va ba trung ((va hanh) OR (va danh)) vi cua triet~.
• Adding a wildcard symbol may retrieve word variants: so sach y nang ma hoi. hieu va ba trung ((va hanh) or (va danh)) vi cua triet*.
