What are the stories of filial piety?

The ancient "twenty-four filial piety" did have myths, true filial piety and foolish filial piety.

There are many stupid filial piety in Twenty-four Filial Pieties, which should be rejected in modern times. For example, Guo Ju buried his son for his mother's sake. Too much filial piety. If he hadn't dug up the gold, his son's life would have been over. Is this filial piety?

The traditional "twenty-four filial piety" is full of "foolish filial piety". In addition to Guo Ju Burying the Son, there are also Sleeping on the Ice to Find Carp, Crying Bamboo Shoots and Mourning the Tomb of Thunder.
