Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
ve triet » va trien, su triet
va triet » va thiet, va trien, cua triet
va thanh » gia thanh, va tinh, le thanh
hieu van » hieu va, thien van, lieu va
van cau » van dau, van hau, van chat
cau xuc » cam xuc, cau luc, cau truc
sach ky » sac ky, sach y, sach ty
tu sach » thu sach, su sach, te sach
x hoi » xa hoi, o hoi, x ho

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 ky nang x hoi. hieu van cau xuc ((va thanh) OR (ban thanh)) vai ((va triet) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang x hoi. hieu van cau xuc ((va thanh) OR (ban thanh)) vai ((va triet) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang x hoi. hieu van cau xuc ((va thanh) OR (ban thanh)) vai ((va triet) or (ve triet))*".
