Perhaps you should try some spelling variations:
te sach » toc sach
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, va danh
ma hoi » mai hoi, xa hoi, me hoi
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao
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 ky nang ((ma hoi) OR (ma hoa)). hieu ((ve cam) OR (va cam)) xuc va hanh vi cua vat~.
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ((ma hoi) or (ma hoa)). hieu ((ve cam) or (va cam)) xuc va hanh vi cua vat*.
