Perhaps you should try some spelling variations:
than cua » nhan cua, thai cua, ban cua
va danh » va dinh, va dan, dia danh
va hanh » van hanh, va thanh, ban hanh
sach ky » sac ky, sach y, sach ty
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sach tu » sach thu, cach tu, sach ty
va bac » van bac, va cac, va bai

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) or (sach tu)) nang xa hoi. lieu va bac xuc ((va hanh) OR (va danh)) than cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach tu)) nang xa hoi. lieu va bac xuc ((va hanh) OR (va danh)) than cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sach tu)) nang xa hoi. lieu va bac xuc ((va hanh) OR (va danh)) than cua tre".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (sach tu)) nang xa hoi. lieu va bac xuc ((va hanh) OR (va danh)) than cua tre*.
