Perhaps you should try some spelling variations:
thanh mot » thanh moi, hanh mot, thanh hoa
thanh mau » hanh mau, thanh hai, thanh ngu
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
cua tre » cua te, cuu tre, cua triet
y sang » _ sang, duy sang
ve cac » va cac, vien cac

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 va ((thanh mot) OR (((thanh mau) OR (thanh san)))) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y sang xa hoi. hieu ve cac duc va ((thanh mot) or (((thanh mau) OR (thanh san)))) cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y sang xa hoi. hieu ve cac duc va ((thanh mot) or (((thanh mau) OR (thanh san)))) cua tre*.
