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

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 ty)) hang xa hoi. hieu va 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 ty)) hang xa hoi. hieu va 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 ty)) hang xa hoi. hieu va cac tac va hanh tai ((cuc tre) or (cuu tre))*".
