Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
dung van » duong van, dung va, dang van
van hanh » van thanh, ban hanh, van anh
su triet » su viet, su tien, ve triet
nang xa » nang x, lang xa, nang ma
van cac » van hac, van bac, dan cac
van cau » van dau, van hau, van chat
su hai » su tai
hai ky » thai ky, hoi ky, hai ly

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

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