Perhaps you should try some spelling variations:
hanh dinh » thanh dinh, hinh dinh, hanh tinh
dinh cuu » dinh chi
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, va danh
ve chat » va chat, van chat
cuu tre » cua tre, cau tren, cau treo
ve cham » va cham, vu cham, ve chim
nang xa » lang xa, nang ma, mang xa
xuc va » duc va, tuc va, luc va

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