Perhaps you should try some spelling variations:
cau triet » cau trieu, su triet, cua triet
thanh lai » thanh hai, thanh lap, thanh loi
va thanh » gia thanh, ban thanh, va tinh
sach ty » sach y, sach tu, sach thu
cua tre » cua te, cuu tre, cua triet
tu sach » thu sach, su sach, te sach
xang xa » lang xa, mang xa, ang xa
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac

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 ty xang xa hoi. hieu ((ve cam) OR (ve cac)) tu va thanh lai ((cua tre) OR (cau triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty xang xa hoi. hieu ((ve cam) OR (ve cac)) tu va thanh lai ((cua tre) or (cau triet))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang xa hoi. hieu ((ve cam) OR (ve cac)) tu va thanh lai ((cua tre) or (cau triet))*.
