Definition: filial piety means to be good to one's parents; to take care of one's parents; to engage in good conduct not just towards parents but also outside the home so as to bring a good name to one's parents and ancestors; to perform the duties of one's job well so as to obtain the material means to support parents as well as carry out sacrifices to the ancestors. –from Wikipedia
Hence, to carry out filial piety a person must respect, appreciate and take care of his/her parents at all time until they pass away. To those who said you had done it by solely celebrating Fathers’ or Mothers’ days, but at other time you are much ‘occupied’ and neglected your parents? Ha-ha, what a laugh.
Sigh, people nowadays started to drain this important value from our cultures. The younger generation shows no appreciation and respect toward the older generations. If this continues, like how can we, the human beings, maintain international integrity and peace through inter-human relationships when we unable to maintain our own families’ warmness? How? What a degrading civilization.
