Perhaps you should try some spelling variations:
danh sai » danh bat, danh dau, hanh san
dung sai » dung tai, dung va, dung dat
bo sach » co sach, hoc sach
sach ty » sach y, sach tu, sach thu
xang x » nang x
v pham » d pham
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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: bo sach ty xang x hoi. hieu ((v pham) OR (vi pham)) duc va ((danh sai) OR (dung sai)) cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo sach ty xang x hoi. hieu ((v pham) or (vi pham)) duc va ((danh sai) OR (dung sai)) cua te~".
• Adding a wildcard symbol may retrieve word variants: bo sach ty xang x hoi. hieu ((v pham) or (vi pham)) duc va ((danh sai) OR (dung sai)) cua te*.
