Perhaps you should try some spelling variations:
te sach » toc sach
va hanh » van hanh, va thanh, va danh
hieu va » lieu va, hieu qua
hieu ve » hieu van
cuu tre » cua tre, cau tren, cau treo
ma hoi » mai hoi, xa hoi, ma hoa
v nang » va nang, vu nang, van nang
y nang » ky nang, ly nang, may nang
xuc va » duc va, tuc va, luc va
vi cuu » vi luu, vinh cuu

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 ((y nang) OR (v nang)) ma hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh vi cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (v nang)) ma hoi. ((hieu ve) or (hieu va)) cam xuc va hanh vi cuu tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) OR (v nang)) ma hoi. ((hieu ve) or (hieu va)) cam xuc va hanh vi cuu tre*.
