Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
qua cham » qua hai, qua cac, va cham
dan vat » dang vat, van vat, dan va
dan vai » dan va, dan tai, den vai
so sach » so sanh, bo sach, co sach
lang ha » long ha
lang xa » dang xay, lang van
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va

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 vai) OR (dan vat)) 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 vai) OR (dan vat)) 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 vai) OR (dan vat)) cua tre*.
