On the horizontal lines are written the words "Lie on the ice to find carp", "Lao Lai entertains his relatives" and "Guo Ju buries his son".

"Lu Xun? There is an article in Morning Flowers called Twenty-four Filial Pieties, which tells the author's feelings when he was a child and reveals the hypocrisy and cruelty of feudal filial piety. The stories of filial piety, such as "Seeking carp on the ice", "Old Lai entertaining relatives" and "Guo Ju burying children", are emphatically analyzed, accusing this feudal filial piety of ignoring children's lives, taking nausea as pleasure, "taking unkindness as a training, slandering ancient evils and teaching future generations ill". The work sharply criticized the tendency of opposing vernacular Chinese and advocating retro at that time.

The so-called Twenty-four Filial Pieties is a book that tells the story of twenty-four filial sons in ancient China. Its main purpose is to promote feudal filial piety. However, among them, "Lao Lai entertains relatives", "Guo Ju buries children" and "fear of tasting dung" are outrageous.

Let's talk about Guo Ju's buried son first. It is said that there was a man named Guo Ju in the Jin Dynasty who was originally very rich. After his father died, he divided his property into two parts and divided it between his two younger brothers. He raised his mother alone and was extremely filial to her. Later, the family became poorer and his wife gave birth to a boy. Guo Ju is worried that raising the child will inevitably affect his mother's support. He discussed with his wife: "The son can be reborn, but the mother can't be resurrected after death. It is better to bury his son and save money to support his mother. " The couple took their son out and dug a hole to bury him. Xing Hao dug up an altar of gold to save his son from death.

Although Guo Ju has filial piety, his behavior of killing children is against human nature, which does not conform to the Confucian concept of "the nature of heaven and earth is precious to human beings". Seemingly filial, but actually cruel. In ancient times, some people sacrificed their lives to pray for God to treat their parents, while others cut meat to satisfy their parents' desire to eat meat. Today, some people offer five zang-organs to treat their parents, but few people kill them. I want to kill my son in order to save food. One is against my mother's love for her grandson, and the other is against my mother's good. Therefore, some people later called this filial piety "foolish filial piety".

Take a casual look at the Twenty-four Filial Piety Pictures, and you will see words such as "selling your body to bury your father", "burying your son to serve your mother" and "crying bamboo shoots". "Carving wood for relatives" and "Burying children for mothers" make people feel heartless; Superstitions such as "Xiaogan moves heaven", "lying on the ice for carp" and "crying bamboo shoots" are serious; "Worried about tasting shit" is disgusting.

Filial piety is justified, pedantry is stupid, blind obedience is sad, and defending morality is hateful.
