Perhaps you should try some spelling variations:
sach ly » sach y, sach ty, sach hay
sach lo » sach dao, sach doi, sach hoi
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
ma hoi » mai hoi, xa hoi, ma hoa
ve cam » ve cham, ve cac, va cam
xuc va » tuc va, luc va, xac 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 ly) OR (sach lo)) nang ma hoi. hieu ve cam ((xuc va) OR (duc va)) hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ly) OR (sach lo)) nang ma hoi. hieu ve cam ((xuc va) or (duc va)) hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ly) OR (sach lo)) nang ma hoi. hieu ve cam ((xuc va) or (duc va)) hanh vi cua tre*.
