Perhaps you should try some spelling variations:
ban hanh » ban hang
cham xuc » cam xuc, chat xuc, pham duc
te sach » toc sach
sach ky » sac ky, sach y, sach ty
hieu va » lieu va, hieu qua
hieu ve » hieu van
sang ma » tang ma, nang ma, sang tao
ky sang » ky nang, ky dang, ky tang
vi cua » vai cua, di cua
cua te » cua tu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky sang ma hoa. ((hieu ve) OR (hieu va)) ((cham xuc) OR (cham soc)) ban hanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky sang ma hoa. ((hieu ve) or (hieu va)) ((cham xuc) OR (cham soc)) ban hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ky sang ma hoa. ((hieu ve) or (hieu va)) ((cham xuc) OR (cham soc)) ban hanh vi cua te*.
