What is Wu's attitude towards feudal morality in his book?

Wu attached great importance to feudal morality, such as filial piety (meaning that younger brother loves older brother), and regarded it as a virtue. However, real life has made him see hypocritical morality. Many scholars differ in their words and deeds, but their actions are just the opposite. In the fifth chapter, for example, Wang De and Wang Ren are church brothers, who are quite talented and "famous figures". What they say verbally is "we students are all working hard for principles", but in fact, all they think about is spending money on snow. If we have money, we can be desperate. In order to fight for the inheritance, Yan set up an heir to prosper the public, but he always said, "We Taigong, these gifts are all right." "We must be confident." The author reveals the current situation that feudal morality is completely bankrupt in the face of money and power with the words and deeds of the characters themselves.
