Perhaps you should try some spelling variations:
chat truc » cau truc, chat xuc
hieu van » hieu va, thien van, lieu va
van chat » cao chat
nang xa » nang x, lang xa, nang ma
sach ky » sac ky, sach ty, sach kem
cua tre » cua te, cuu tre, cua triet
va dan » va dao, va dau, va dap
ca dan » cac dan, ca dao

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: thu ((sach ky) OR (sach y)) nang xa hoi. hieu van chat truc ((va dan) OR (ca dan)) dai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) or (sach y)) nang xa hoi. hieu van chat truc ((va dan) OR (ca dan)) dai cua tre~".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) or (sach y)) nang xa hoi. hieu van chat truc ((va dan) OR (ca dan)) dai cua tre*.
