Filial piety is still of significant importance in Asia but especially in Korea-at less I know. When I think of filial piety it's probobably no coincidence that my mind wonders to one of my older sisters', when my birthparents were busy with trying to provide for their groving family this sister took on the role of caring for the younger children. She would probably have taken care of me as well and helped to raise me-she seemed happy to look after them yet I think it had more to do with the fact that she had no choice. She was expected to that and as a filial daughter she agreed to it.
Not until 15 years later did she consider dating in the hopes of being someone's wife and future mother. The reason for that is that by now the youngest sibling had gone of to College. My sister eventually begun dating a fairly successful athlete-evidently he was promised a successful career in his chosen field but instead of going overseas he chose my sister and a future in Korea. Eventually birthfather begun to contemplate that the end of his life was approching and he expressed that he wished my sister would give him grandchild.
With my birthfather's blessing my sister and the athlete eventually had an out of wedlock child but married before the child was born. They are still married to this day-but I personally don't think I would be willing to accept doing something out of filial piety because I was not raised in such a culture and those values are more or less foreign to me. Not that there wasn't a time where I tried to fulfill the same expections of filial piety that my birthparents evidently had for their remaining children. The children that they raised.
