Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
danh vai » danh sai, danh va, doanh van
cham xuc » cam xuc, chat xuc, cham soc
dang xay » dang van, van xay
vai cua » dai cua, hai cua, lai cua
va danh » va dinh, va dan, va hanh
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
lang xa » lang ha, 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: ((te sach) OR (toc sach)) hoi ((lang xa) OR (dang xay)) hoi. hieu ve cham xuc va danh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) hoi ((lang xa) or (dang xay)) hoi. hieu ve cham xuc va danh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) hoi ((lang xa) or (dang xay)) hoi. hieu ve cham xuc va danh vai cua tre*.
