After getting rid of the fetters of Buddhist funeral rituals

the Confucians in the Edo Period (1603-1868) of Japan fully accepted Chu Hsi's Family Rituals and actively advocated the idea of "ancient connotations" in the Tao of Sage

and established the concept of life and death on the daily practice of the ceremony of "family rituals"

which was of great importance for accepting Shushigaku in the Japanese society. At the same time

in order to further localize the Confucian life etiquette

and demonstrate the legitimacy of the family rituals in the Edo Period and China's Confucian orthodoxy

the intellectuals of the Kogaku School represented by Ito Jinsai (伊藤仁斋) and Ogyu Sorai (荻生徂徕) advocated to divert from the Confucian integration of ceremony and rationalism that "Rituals are rules of the heaven and etiquette of the people"

and re-understand the relationship between the Confucian orthodoxy and the way of filial piety in family rituals from the perspective of "Dao Zhe Tong Ming" (道者统名) and tried to prove the "Japanization" of Chinese Confucianism on the basis of criticizing the Confucian theory of rituals of the Song Dynasty. The essence of the Kogaku School is to redefine "the concept of the Chinese and the Foreign" in the East Asian Confucianist world through localizing family rituals

and to deconstruct "culture of the other" while advocating Ethno-centralism" .
