Filial Piety, Filial Piety and Lastly, Still Filial

"The three elements of children's treatment of parents are filial piety, filial piety and lastly, still filial piety.  We can never fully repay the kindness to our parents.  To be filial is not to provide materially, making our parents is the greatest act of filial piety.  Filial piety is not only the yardstick for personal behaviour and family management, but the core yardstick for personal behaviour and family management, but the core guiding principle in running a country and bring harmony to the world.  It is a universal and perennial fundamental value.
