Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
danh vi » hanh vi, danh di, danh va
dinh vi » dinh ve, dinh viet, dinh tri
hieu ve » hieu va, hieu van
cac thu » cach thuc, cac thoi
thu va » thuc va, thue va, tu va
tai ky » thai ky, trai ky, sai ky
ve cac » va cac, vien cac
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 va ((danh vi) OR (dinh 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 va ((danh vi) OR (dinh 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 va ((danh vi) OR (dinh vi)) ((cua triet) or (su triet))*".
