Perhaps you should try some spelling variations:
ve triet » va trien, su triet
hieu van » hieu va, thien van, lieu va
hanh lam » thanh lap, hanh kem, hanh va
xa hanh » xa thanh, xa khanh, va hanh
nang xa » nang x, lang xa, nang ma
cau tuc » cau truc, cau luc, cau phuc
cau tu » dau tu, cau truc
lam ve » la ve, lam vu, nam ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((so sanh) or (do sanh)) ky nang xa hoi. hieu van ((cau tuc) OR (cau tu)) xa hanh lam ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (do sanh)) ky nang xa hoi. hieu van ((cau tuc) OR (cau tu)) xa hanh lam ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) or (do sanh)) ky nang xa hoi. hieu van ((cau tuc) OR (cau tu)) xa hanh lam ve triet".
• Adding a wildcard symbol may retrieve word variants: ((so sanh) or (do sanh)) ky nang xa hoi. hieu van ((cau tuc) OR (cau tu)) xa hanh lam ve triet*.
