Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
hang tai » hang va, dung tai
so sach » so sanh, bo sach, co sach
sach ty » sach y, sach tu, sach thu
hanh va » hang va, hanh vi
cau luc » cau truc, cau phuc
cau xuc » cam xuc, cau truc, chat xuc
xang xa » lang xa, mang xa, ang xa
cua tre » cua te, cuu tre, cua triet

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 ty xang xa hoi. hieu van ((cau xuc) OR (cau luc)) van ((hang tai) OR (hanh va)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty xang xa hoi. hieu van ((cau xuc) OR (cau luc)) van ((hang tai) or (hanh va)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: so sach ty xang xa hoi. hieu van ((cau xuc) OR (cau luc)) van ((hang tai) or (hanh va)) cua tre*.
