Perhaps you should try some spelling variations:
ban thanh » ban hanh
va triet » va thiet, va trien, ve triet
ban hang » ngan hang
hieu van » hieu va, thien van, lieu va
tu sach » thu sach, te sach, tu cach
cau xuc » cam xuc, cau luc, cau truc
nang xa » nang x, lang xa, nang ma
su sach » so sach, vu sach
van cau » van dau, van hau, van chat
hai va » hai van, thai va, hoi va

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (su sach)) ky nang xa hoi. hieu van cau xuc ((ban thanh) OR (ban hang)) hai va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky nang xa hoi. hieu van cau xuc ((ban thanh) OR (ban hang)) hai va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ky nang xa hoi. hieu van cau xuc ((ban thanh) OR (ban hang)) hai va triet*".
