Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
cham xuc » chat xuc, cham soc, pham duc
dua tren » dung tren
lang hai » lang chai, lang thai, lang ha
tinh lai » tinh lao, tinh hai, minh lai
va tinh » may tinh
cua tre » cua te, cuu tre, cua triet
sach ty » sach y, sach tu, sach thu
hieu ve » hieu va, hieu van
hai hoi » dai hoi, hai moi, hai hai
ty lang » tay lang, ty xang, ty hang

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: toc sach ty lang hai hoi. hieu ve ((cham xuc) OR (cam xuc)) va tinh lai ((dua tren) OR (cua tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty lang hai hoi. hieu ve ((cham xuc) OR (cam xuc)) va tinh lai ((dua tren) or (cua tre))~".
• Adding a wildcard symbol may retrieve word variants: toc sach ty lang hai hoi. hieu ve ((cham xuc) OR (cam xuc)) va tinh lai ((dua tren) or (cua tre))*.
