Perhaps you should try some spelling variations:
ban hanh » ban hang
dua tren » dung tren
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
va cham » va chat
va tham » van tham, va thanh, va thuat
xuc ban » duc ban, cuc ban, quoc ban
cua tu » cua tuc, cua su, cua cu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty xang xa hoi. hieu ((va cham) OR (va tham)) xuc ban hanh vi ((dua tren) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty xang xa hoi. hieu ((va cham) OR (va tham)) xuc ban hanh vi ((dua tren) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty xang xa hoi. hieu ((va cham) OR (va tham)) xuc ban hanh vi ((dua tren) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: su sach ty xang xa hoi. hieu ((va cham) OR (va tham)) xuc ban hanh vi ((dua tren) or (cua tu))*.
