Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
xuc ban » duc ban, cuc ban, quoc ban
xuc van » duc van, luc van, thuc van
cua tre » cua te, cuu tre, cua triet
nang xa » lang xa, nang ma, mang xa
hieu ve » hieu va, hieu van
anh ca » danh ca, anh cam, anh cua
ca cua » co cua
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y ((nang xa) OR (nang x)) hoi. hieu ve cac ((xuc van) or (xuc ban)) anh ca cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (nang x)) hoi. hieu ve cac ((xuc van) OR (xuc ban)) anh ca cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((nang xa) OR (nang x)) hoi. hieu ve cac ((xuc van) or (xuc ban)) anh ca cua tre*".
