Perhaps you should try some spelling variations:
sach kem » hanh kem
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
va tinh » may tinh
tinh de » tinh da, sinh de, tinh he
cua tre » cua te, cuu tre, cua triet
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 hoi. hieu van cam xuc va tinh de cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu ((sach kem) or (sac ky)) nang xa hoi. hieu van cam xuc va tinh de cua tre*.
