Perhaps you should try some spelling variations:
te sach » toc sach
sach ky » sac ky, sach y, sach ty
hieu va » lieu va, hieu qua
nam tuc » nam thuc, nam truc, nam tu
xa hanh » xa thanh, xa khanh, va hanh
cua tre » cua te, cuu tre, cua triet
ma hoi » mai hoi, xa hoi, me hoi
va nam » van nam, ha nam, va nay
vi cua » vai cua, di cua

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((ma hoi) OR (ma hoa)). hieu va nam tuc xa hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ((ma hoi) OR (ma hoa)). hieu va nam tuc xa hanh vi cua tre*.
