Perhaps you should try some spelling variations:
thanh dam » thanh dat, thanh nam, thanh tam
ban thanh » ban hanh, ban hang
va triet » va thiet, va trien, ve triet
sach bai » sach dao, cac bai, sach xa
sach tai » sach tham, sach dao, sach xa
ve cham » va cham, ve chat, vu cham
xuc ban » duc ban, cuc ban, quoc ban
hanh xa » hanh va, hanh ma, hanh xu
dam va » dam van, nam va, dam ha
ve cam » ve cac, va cam, ve cai

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

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