Perhaps you should try some spelling variations:
te sach » toc sach
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua

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 ((ma hoa) OR (mai hoi)). hieu ve cac xuc va hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((ma hoa) or (mai hoi)). hieu ve cac xuc va hanh vi cua tre*.
