Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
dung tren » dung trong, dung trung
sach thu » sach thue, sach thieu, sach tham
va thanh » gia thanh, ban thanh, va tinh
ve pham » vi pham, v pham, ve phan
hieu ve » hieu va, hieu van
sach ty » sach y, sach tu, xach tay
nang ma » tang ma, sang ma, nang cao
cuu tre » cua tre, cau tren, cau treo
ma hoi » mai hoi, xa hoi, ma hoa

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 ty) OR (sach thu)) nang ma hoi. hieu ve pham duc va thanh lai ((dung tren) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach thu)) nang ma hoi. hieu ve pham duc va thanh lai ((dung tren) or (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach thu)) nang ma hoi. hieu ve pham duc va thanh lai ((dung tren) or (cuu tre))*.
