Perhaps you should try some spelling variations:
te sach » toc sach
nang ma » tang ma, sang ma, nang cao
va cham » va tham
va chat » van chat, va phat, cao chat
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
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 y nang ma hoa. lieu ((va cham) OR (va chat)) hoc va danh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoa. lieu ((va cham) OR (va chat)) hoc va danh vi cua tre*.
