Perhaps you should try some spelling variations:
sach thu » sach thue, sach thieu, sach tham
thu xang » thu hang, thu bang, thu dang
hieu van » hieu va, thien van, lieu va
cac nuoc » cap nuoc, hoc nuoc, dat nuoc
su sach » so sach, vu sach

cac xuc » cam xuc, chat xuc, cac cuoc
va hanh » van hanh, va thanh, va danh

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: su sach thu xang xa hoi. hieu van ((cac xuc) OR (cac nuoc)) va hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: su sach thu xang xa hoi. hieu van ((cac xuc) or (cac nuoc)) va hanh vi cua tre*.
