Perhaps you should try some spelling variations:
hang tai » hang va, dung tai
hanh tai » thanh tai, han tai, hinh tai
so sach » so sanh, bo sach, co sach
hang xa » hoang xa, hang va, hang ca
cua tre » cua te, cuu tre, cua triet
ve cac » va cac, vien cac
y hang » ly hang, ty hang, yu hang
xuc va » duc va, tuc va, luc va
ve cam » ve cham, va cam, ve cai

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