Perhaps you should try some spelling variations:
te sach » toc sach
tang ma » mang may, tang van
hieu ve » hieu va, hieu van
hanh va » hanh vi
cua tre » cua te, cuu tre, cua triet
y tang » ky tang, 6 tang, 7 tang
ma hoi » mai hoi, xa hoi, ma hoa
ve cam » ve cham, ve cac, va cam
xuc va » tuc va, luc va, xac va

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