Perhaps you should try some spelling variations:
tinh dau » tinh da, trinh dan, trinh dao
te sach » toc sach
sang xa » song xa, lang xa, sang ma
hieu ve » hieu va, hieu van
cac duc » cac du, cao duc, cac dac
va tinh » may tinh
cua tre » cuu tre, cua triet, dua tren
y sang » _ sang, duy sang
cua te » cua tu

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 sang xa hoi. hieu ve ((cac duc) OR (giao duc)) va tinh dau ((cua tre) OR (cua te))~.
• Adding a wildcard symbol may retrieve word variants: te sach y sang xa hoi. hieu ve ((cac duc) or (giao duc)) va tinh dau ((cua tre) or (cua te))*.
