Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
sach kem » hanh kem
hieu van » hieu va, thien van, lieu va
thanh de » hanh de, thanh ve, thanh do
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
xuc ban » duc ban, cuc ban, quoc ban
cua tre » cua te, cuu tre, cua triet
de cua » le cua, te cua, dieu cua

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: tu ((sach kem) OR (cac ky)) nang xa hoi. hieu van cam xuc ban thanh de cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu ((sach kem) or (cac ky)) nang xa hoi. hieu van cam xuc ban thanh de cua tre*.
