Perhaps you should try some spelling variations:
cach thuc » anh thuc
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hieu ve » hieu va, hieu van
cac thu » cac thoi
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
tai ky » thai ky, trai ky, sai ky
su tai » su thi, tu tai
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 tai ky nang x hoi. hieu ve ((cac thu) OR (cach thuc)) va danh vi ((cua triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su tai ky nang x hoi. hieu ve ((cac thu) OR (cach thuc)) va danh vi ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su tai ky nang x hoi. hieu ve ((cac thu) OR (cach thuc)) va danh vi ((cua triet) or (su triet))*".
