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