Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, le thanh
te sach » toc sach
dat cua » dai cua, day cua, mat cua
va tinh » may tinh
cua tre » cua te, cuu tre, cua triet
lang xa » lang ha, dang xay, lang van
y lang » o lang, _ lang, tay lang
va cam » va cham, va cac, va cao
va dao » ca dao

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 y lang xa hoi. hieu ((va cam) or (va dao)) truc ((va thanh) OR (va tinh)) dat cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang xa hoi. hieu ((va cam) OR (va dao)) truc ((va thanh) OR (va tinh)) dat cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang xa hoi. hieu ((va cam) or (va dao)) truc ((va thanh) OR (va tinh)) dat cua tre*".
