Against today’s backdrop of "filial piety" in society, the “filial piety” in the Analects of Confucius triggered heated debates. Since ancient times, “filial piety”, which is of great importance to traditional Chinese culture, has been an important part of Confucianism. “Ingratitude” will inevitably be condemned by society. But nowadays, “irrational filial piety” will turn into “foolish filial piety”. Therefore, what people should do is to carry out "rational filial piety" and carry forward Chinese traditional culture critically so as to make contribution to building a harmonious socialist society.
