Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
cua triet » cua viet, su triet, va triet
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, va danh
van ha » van chat, van hanh, van phan
x hoi » xa hoi, o hoi, x ho

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 ky nang x hoi. hieu ((van ha) OR (van hoa)) xuc ((va hanh) or (van thanh)) dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang x hoi. hieu ((van ha) OR (van hoa)) xuc ((va hanh) OR (van thanh)) dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang x hoi. hieu ((van ha) OR (van hoa)) xuc ((va hanh) or (van thanh)) dai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang x hoi. hieu ((van ha) OR (van hoa)) xuc ((va hanh) or (van thanh)) dai cua triet*.
