Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
van hanh » van thanh, ban hanh, van anh
so sach » so sanh, bo sach, co sach
hoa xuc » hoa xua, hoa xu, hoa duoc
va danh » va dinh, va dan, va hanh
y nang » ky nang, ly nang, v nang
x hoi » xa hoi, o hoi, x ho

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang x hoi. hieu van hoa xuc ((va danh) OR (van hanh)) dai cua triet~".
• Adding a wildcard symbol may retrieve word variants: so sach y nang x hoi. hieu van hoa xuc ((va danh) OR (van hanh)) dai cua triet*.
