Why Lu Xun said that ritualism is a "cannibalistic" ritualism

Because for thousands of years, Confucianism, as the dominant culture in China, has spared no effort to limit, cage, and satisfy people's behaviors and emotions within a certain set of rules and regulations with its complicated rules and ethics, and the individual has been weaved into a big net of crisscrossing patriarchal relationships. Ethics, as the overall appearance of the country and society, is commonplace as the spiritual shackles of human beings, greatly annihilating the connotation and significance of the individual self. Mr. Lu Xun said "cannibalism" is actually eating the human subject consciousness and independent personality.
