Perhaps you should try some spelling variations:
thuc van » thuc vat, thuc dan, thuc va
te sach » toc sach
va cham » va chat, va tham
anh dai » vanh dai, anh bai, anh dat
tuc van » truc van, tuc va, duc van
hieu va » lieu va, hieu qua
sach ty » sach y, sach tu, sach thu
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
cua tre » cua te, cuu tre, cua triet

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (lang xa)) hoi. hieu va cham ((tuc van) OR (thuc van)) anh dai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) or (lang xa)) hoi. hieu va cham ((tuc van) OR (thuc van)) anh dai cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) or (lang xa)) hoi. hieu va cham ((tuc van) OR (thuc van)) anh dai cua tre*.
