Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, doanh tai
dang mau » dong mau, dang van, dang su
te sach » toc sach
ve cham » va cham, ve chat, vu cham
tai cua » thai cua, tai cuc, tri cua
xuc gia » duc gia, luc gia, tuc gia
cua tre » cua te, cuu tre, cua triet
sach ky » sac ky, sach y, sach ty
mau hoi » cau hoi, mai hoi, mau ho
ky dang » ky nang, ky danh
ve cac » va cac, vien cac
ve cam » va cam, ve cai, ve cau

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 dang mau hoi. hieu ((((ve cam) OR (ve cac))) OR (ve cham)) xuc gia thanh tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dang mau hoi. hieu ((((ve cam) OR (ve cac))) or (ve cham)) xuc gia thanh tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ky dang mau hoi. hieu ((((ve cam) OR (ve cac))) or (ve cham)) xuc gia thanh tai cua tre*.
