Perhaps you should try some spelling variations:
sach kem » hanh kem
thanh de » hanh de, thanh ve, thanh do
va thanh » gia thanh, ban thanh, va tinh
hieu van » hieu va, thien van, lieu va
van cam » van nam, van lam, van cau
cua tre » cua te, cuu tre, cua triet
nang xa » lang xa, nang ma, mang xa
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
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 (sac ky)) ((nang xa) OR (nang x)) hoi. hieu van cam xuc va thanh de cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (sac ky)) ((nang xa) OR (nang x)) hoi. hieu van cam xuc va thanh de cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach kem) or (sac ky)) ((nang xa) OR (nang x)) hoi. hieu van cam xuc va thanh de cua tre*.
