Perhaps you should try some spelling variations:
cac thuc » cach thuc, cac thu, can thuc
te sach » toc sach
sach tu » sach thu, cach tu, sach ty
hanh de » hanh ve, hanh kem
xanh di » vanh dai, xanh tai
danh di » danh du, danh dien, danh gia
thuc va » thuc vat, thuc dan, thuc day
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
tu nang » tru nang, tu nong, tu nano
cua te » cua tu

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 tu nang xa hoi. hieu va cac thuc va ((((danh di) OR (xanh di))) OR (hanh de)) cua te~.
• Adding a wildcard symbol may retrieve word variants: te sach tu nang xa hoi. hieu va cac thuc va ((((danh di) or (xanh di))) or (hanh de)) cua te*.
