Perhaps you should try some spelling variations:
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
tinh cuu » trinh cuu, dinh cuu, tinh cua
sach ky » sac ky, sach ty, sach kem
va hanh » van hanh, va thanh, va danh
cuu tre » cua tre, cau tren, cau treo
lang xa » lang ha, dang xay, lang van
ve bao » te bao, va bao
ve co » vo co, va co, de co

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 ky) OR (sach y)) lang xa hoi. hieu ((ve co) or (ve bao)) duc va hanh tinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) lang xa hoi. hieu ((ve co) OR (ve bao)) duc va hanh tinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) lang xa hoi. hieu ((ve co) or (ve bao)) duc va hanh tinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) lang xa hoi. hieu ((ve co) or (ve bao)) duc va hanh tinh cuu tre*.
