Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
va tinh » may tinh
hieu ve » hieu va, hieu van
cam luc » cam xuc, cau luc
va hanh » van hanh, va thanh, va danh
tai ky » thai ky, trai ky, sai ky
ve cam » ve cham, ve cac, va cam
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: te tai ky nang x hoi. hieu ve cam luc ((va hanh) or (va tinh)) vi ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te tai ky nang x hoi. hieu ve cam luc ((va hanh) OR (va tinh)) vi ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te tai ky nang x hoi. hieu ve cam luc ((va hanh) or (va tinh)) vi ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: te tai ky nang x hoi. hieu ve cam luc ((va hanh) or (va tinh)) vi ((cua triet) OR (su triet))*.
