Perhaps you should try some spelling variations:
te sach » toc sach
cua tre » cua te, cuu tre, cua triet
nang ma » tang ma, sang ma, nang cao
ve cam » ve cham, va cam, ve cai
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc va
vi cua » vai cua, di cua
ve cac » va cac, vien cac

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