Perhaps you should try some spelling variations:
dinh lai » dinh lam, dinh lap, dinh tai
sach ty » sach y, sach thu, xach tay
sach tu » sach thu, cach tu, sach uu
hieu ve » hieu va, hieu van
ve pham » vi pham, v pham, ve phan
va dinh » van dinh, va kinh, va tinh
lai cua » dai cua, hai cua, lai chau
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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: so ((sach ty) OR (sach tu)) nang x hoi. hieu ve pham duc va dinh lai cua te~.
• Adding a wildcard symbol may retrieve word variants: so ((sach ty) or (sach tu)) nang x hoi. hieu ve pham duc va dinh lai cua te*.
