Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
sach ly » sach lo, sach ty, sach hay
cuc tre » duc tre, cua tre, cuc thue
va hanh » van hanh, va thanh, va danh
cac tac » cac toc, cac bac, cac dac
cuu tre » cua tre, cau tren, cau treo
hieu ve » hieu va, hieu van
hang xa » hoang xa, hang va, hang ca
tac va » tac da, tac xa, tuc va
ve cac » va cac, vien cac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((sach ly) OR (sach y)) hang xa hoi. hieu ve cac tac va hanh tai ((cuc tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((sach ly) OR (sach y)) hang xa hoi. hieu ve cac tac va hanh tai ((cuc tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((sach ly) OR (sach y)) hang xa hoi. hieu ve cac tac va hanh tai ((cuc tre) or (cuu tre))*".
