Perhaps you should try some spelling variations:
ve triet » va trien, su triet
cuu tre » cua tre, cau tren, cau treo
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
cam duc » cam xuc, cao duc, pham duc
sach ty » sach y, sach tu, sach thu
tu sach » thu sach, su sach, te sach
nang xa » lang xa, nang ma, mang xa
va cam » va cham, va cac, va cao

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 ty ((nang xa) OR (nang x)) hoi. lieu va cam duc va hanh di ((cuu tre) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang xa) OR (nang x)) hoi. lieu va cam duc va hanh di ((cuu tre) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang xa) OR (nang x)) hoi. lieu va cam duc va hanh di ((cuu tre) or (ve triet))*".
