Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
quoc ban » quoc bao, quoc lan, quoc quan
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
van lam » van nam
xuc ban » duc ban, cuc ban, xuat ban
cua tre » cuu tre, cua triet, dua tren
anh vi » hanh vi, anh va, anh ve
cua te » cua tu

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 ty xang xa hoi. hieu van lam ((xuc ban) OR (quoc ban)) anh vi ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty xang xa hoi. hieu van lam ((xuc ban) OR (quoc ban)) anh vi ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty xang xa hoi. hieu van lam ((xuc ban) OR (quoc ban)) anh vi ((cua tre) or (cua te))*".
