Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hieu ve » hieu va, hieu van
va dinh » van dinh, va kinh, va tinh
dinh vi » dinh ve, dinh viet, dinh tri
su tai » su thi
ve dam » ven dam, ke dam, va dam
dam tu » nam tu, cam tu, tam tu
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) OR (tu tai)) ky nang x hoi. hieu ve 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) OR (tu tai)) ky nang x hoi. hieu ve 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) OR (tu tai)) ky nang x hoi. hieu ve dam tu va dinh vi ((cua triet) or (su triet))*".
