Perhaps you should try some spelling variations:
ban hanh » ban hang
hoc sach » hoc sinh, hoc cac, hoc anh
cham xuc » cam xuc, chat xuc, cham soc
xuc ban » duc ban, cuc ban, quoc ban
te sach » toc sach
nang xa » nang x, lang xa, nang ma
vu nang » vuc nang, va nang, vu dang
va cham » va chat, va tham
vi ve » va ve, gi ve, vi he
ve ve » de ve, va ve, ke ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (hoc sach)) vu nang xa hoi. lieu va cham xuc ban hanh ((vi ve) OR (ve ve)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (hoc sach)) vu nang xa hoi. lieu va cham xuc ban hanh ((vi ve) OR (ve ve)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (hoc sach)) vu nang xa hoi. lieu va cham xuc ban hanh ((vi ve) OR (ve ve)) triet*".
