Perhaps you should try some spelling variations:
thanh lap » thanh san, phan lap, thanh hai
toc sach » hoc sach, doc sach, thuoc sach
va thanh » gia thanh, ban thanh, va tinh
hieu ve » hieu va, hieu van
lap cua » lai cua, tap cua, lam cua
cam luc » cam xuc, cau luc
ky tang » ky nang, ky dang, kho tang
ky sang » ky nang, ky dang, duy sang
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
luc va » duc va, tuc va, loc 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)) ((ky sang) OR (ky tang)) xa hoi. hieu ve cam luc va thanh lap cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ((ky sang) or (ky tang)) xa hoi. hieu ve cam luc va thanh lap cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) ((ky sang) or (ky tang)) xa hoi. hieu ve cam luc va thanh lap cua tre*.
