Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
hoc sach » hoc sinh, hoc cac, hoc anh
va thanh » gia thanh, ban thanh, va tinh
dang mam » dang nam, dang mau, dang mat
cua tre » cuu tre, cua triet, dua tren
sach ky » sac ky, sach y, sach ty
hieu va » lieu va, hieu qua
dang ma » dang mau, dang mat, tang ma
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
cua te » cua tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc sach ky ((dang ma) OR (dang mam)) hoi. hieu va cam xuc va thanh vai ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach ky ((dang ma) OR (dang mam)) hoi. hieu va cam xuc va thanh vai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach ky ((dang ma) OR (dang mam)) hoi. hieu va cam xuc va thanh vai ((cua tre) or (cua te))*".
