Perhaps you should try some spelling variations:
te sach » toc sach
sach ty » sach y, sach tu, sach thu
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
cac duc » cac du, cao duc, cac dac
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((nang xa) or (lang xa)) hoi. lieu va cac duc ((va hanh) OR (va danh)) di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (lang xa)) hoi. lieu va cac duc ((va hanh) OR (va danh)) di cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) or (lang xa)) hoi. lieu va cac duc ((va hanh) OR (va danh)) di cua tre*".
