Perhaps you should try some spelling variations:
pham thuc » phap thuc, pham chuc, nham thuc
thanh lai » thanh hai, thanh lap, thanh loi
va thanh » gia thanh, ban thanh, va tinh
sach cu » sach cua, sach uu, sach xu
thuc va » thuc vat, thuc dan, thuc day
ve pham » vi pham, v pham, ve phan
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
sach tu » sach thu, cach tu, sach ty
cuu tre » cua tre, cau tren, cau treo
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: tu ((sach cu) OR (sach tu)) lang xa hoi. hieu ve pham thuc va thanh lai ((cua te) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach cu) OR (sach tu)) lang xa hoi. hieu ve pham thuc va thanh lai ((cua te) or (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach cu) OR (sach tu)) lang xa hoi. hieu ve pham thuc va thanh lai ((cua te) or (cuu tre))*.
