Perhaps you should try some spelling variations:
hoc sach » hoc sinh, hoc cac
cham xuc » cam xuc, chat xuc, cham soc
ban hanh » ban hang
ve triet » va trien, su triet
te sach » toc sach
hoc anh » hoc nganh, hoc nhanh, ngoc anh
vu nang » vuc nang, va nang, vu dang
va cham » va chat, va tham
xuc ban » duc ban, cuc ban, quoc ban
x hoi » xa hoi, o hoi, x ho
vi ve » va ve, gi ve, ve 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) OR (hoc anh)))) vu nang x hoi. lieu va cham xuc ban hanh vi ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (((hoc sach) OR (hoc anh)))) vu nang x hoi. lieu va cham xuc ban hanh vi ve triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (((hoc sach) OR (hoc anh)))) vu nang x hoi. lieu va cham xuc ban hanh vi ve triet*".
