Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
qua cham » qua hai, qua cac, va cham
vai cua » dai cua, hai cua, lai cua
so sach » so sanh, bo sach, co sach
lang xa » dang xay, lang van
lang ha » long ha
cua tre » cua te, cuu tre, cua triet
va dan » ca dan, va dau, va dap
va dao » 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: so sach y ((lang xa) OR (lang ha)) hoi. hieu qua cham xuc ((va dan) OR (va dao)) vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y ((lang xa) or (lang ha)) hoi. hieu qua cham xuc ((va dan) OR (va dao)) vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: so sach y ((lang xa) or (lang ha)) hoi. hieu qua cham xuc ((va dan) OR (va dao)) vai cua tre*.
