Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
va dinh » van dinh, va kinh, va tinh
dinh vi » dinh ve, dinh viet, dinh tri
su tai » su thi, tu tai
tai ky » thai ky, trai ky, sai ky
ve dam » ven dam, va dam, ve dao
ke dam » ke dan
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 dam) OR (ke dam)) tu va 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 dam) OR (ke dam)) tu va 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 dam) OR (ke dam)) tu va dinh vi ((cua triet) or (su triet))*".
