Perhaps you should try some spelling variations:
ve triet » va trien, su triet
va triet » va thiet, va trien, cua triet
va hang » van hang, va nang, va lang
hang di » hang doi, hang vi, hang dien
tu sach » thu sach, su sach, te sach
dang xa » dang xay, lang xa, dang ha
y dang » ky dang, 2 dang, _ dang
tuc va » thuc va, truc va, tuc xa
ve cac » vien cac

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 y dang xa hoi. hieu ((ve cac) OR (va cac)) tuc va hang di ((va triet) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang xa hoi. hieu ((ve cac) OR (va cac)) tuc va hang di ((va triet) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang xa hoi. hieu ((ve cac) OR (va cac)) tuc va hang di ((va triet) or (ve triet))*".
