Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hieu van » hieu va, thien van, lieu va
van hanh » van thanh, ban hanh, van anh
hanh de » hanh ve, hanh kem
hieu ve » hieu va
nang xa » nang x, lang xa, nang ma
su cac » tu cac, su cao, su can
tu van » tu va
cam tu » cam thu, nam tu, dam tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su cac ky nang xa hoi. ((hieu ve) or (hieu van)) cam tu van hanh de ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac ky nang xa hoi. ((hieu ve) OR (hieu van)) cam tu van hanh de ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac ky nang xa hoi. ((hieu ve) or (hieu van)) cam tu van hanh de ((cua triet) OR (su triet))*".
