Perhaps you should try some spelling variations:
thanh tien » thanh vien, thanh nien, thang tien
thien van » thi van
ve triet » va trien, su triet
nam truc » nam truoc, nam thuc, nam trung
va thanh » gia thanh, ban thanh, va tinh
tien ve » tien te, tien va, dien ve
nam tuc » nam thuc, nam tu, nam thuoc
nang xa » nang x, lang xa, nang ma
tu san » thu san, tu ban, tu can
tu bac » tu ban, tu cac, tu bat

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu bac) or (tu san)) ky nang xa hoi. thien van ((nam tuc) OR (nam truc)) va thanh tien ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu bac) OR (tu san)) ky nang xa hoi. thien van ((nam tuc) OR (nam truc)) va thanh tien ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu bac) or (tu san)) ky nang xa hoi. thien van ((nam tuc) OR (nam truc)) va thanh tien ve triet".
• Adding a wildcard symbol may retrieve word variants: ((tu bac) or (tu san)) ky nang xa hoi. thien van ((nam tuc) OR (nam truc)) va thanh tien ve triet*.
