Perhaps you should try some spelling variations:
than cua » nhan cua, thai cua, ban cua
than cuu » than cui, thanh luu, thang cua
su sach » so sach, vu sach
va hanh » van hanh, va thanh, va danh
sach ty » sach y, sach tu, sach thu
van cau » van dau, van hau, van chat
van cac » van hac, van bac, dan cac
xang xa » lang xa, mang xa, ang xa
xuc va » duc va, tuc va, luc va

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 ((van cac) or (van cau)) xuc va hanh ((than cuu) OR (than cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty xang xa hoi. hieu ((van cac) OR (van cau)) xuc va hanh ((than cuu) OR (than cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty xang xa hoi. hieu ((van cac) or (van cau)) xuc va hanh ((than cuu) OR (than cua)) tre".
• Adding a wildcard symbol may retrieve word variants: su sach ty xang xa hoi. hieu ((van cac) or (van cau)) xuc va hanh ((than cuu) OR (than cua)) tre*.
