Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
so sach » so sanh, bo sach, co sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
van cac » van hac, van cau, van bac
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
lai cua » dai cua, hai cua, lai chau
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty xang xa hoi. hieu van cac ((xuc van) OR (duc van)) dinh ((di cua) or (lai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty xang xa hoi. hieu van cac ((xuc van) OR (duc van)) dinh ((di cua) OR (lai cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty xang xa hoi. hieu van cac ((xuc van) OR (duc van)) dinh ((di cua) or (lai cua)) te*".
