Perhaps you should try some spelling variations:
duy sang » duy van, duy can, duy anh
danh vai » danh sai, danh va, doanh van
te sach » toc sach
hieu ve » hieu va, hieu van
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
y sang » _ sang
ve cac » va cac, vien cac
xuc va » tuc va, luc va, xac va

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