Perhaps you should try some spelling variations:
thien van » thi van
sach kem » hanh kem
thanh de » hanh de, thanh ve, thanh do
cau luc » cau truc, cau phuc
cau xuc » cam xuc, cau truc, chat xuc
cua tre » cua te, cuu tre, cua triet
de cua » le cua, te cua, dieu cua
sac ky » cac ky, sai ky
x hoi » xa hoi, o hoi, x ho

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 x hoi. thien van ((cau xuc) OR (cau luc)) gia thanh de cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (sac ky)) nang x hoi. thien van ((cau xuc) OR (cau luc)) gia thanh de cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach kem) or (sac ky)) nang x hoi. thien van ((cau xuc) OR (cau luc)) gia thanh de cua tre*.
