The two words “Xiao”（love and respect for Parents）and “Ti”（love and respect for elder brothers）in Confucianism，have different prescriptive and are mutual intermediated，with a gap in meaning but a unity. “Xiao” reflects the children’s respect and responsibility to their parents. Of course it takes the kinship as the core，but also it includes the filial piety to all the seniors. In Confucianism it prescribes the “Ti” from a narrow angle as a “brotherhood”，and “Ti” also has the meaning of “order” or “sequence”. Filial piety becomes the cornerstone of Confucian ethics and “Ti” is regarded as a fundamental moral benevolence. Filial piety is the ethical endowments that makes personal growth and development，and is the important emotional bond that maintains family relationships，and also it is the value rationality that achieves the governing and prosperity of the nation. “Ti” has the same function as “Xiao” that can maintain a social relationship，and promote social stability. To solve the problem of Confucian morality of filial piety with modern social integration and conflict，and to realize the modern transformation of Confucian filial piety ethics，we must trace back its sources and make a correct survey of the core idea of the true moral principles. To comprehensively and accurately evaluate the social role and its impact of the Confucian filial piety，we should appraise it from the three dimensions：its universality and particularity，monism and pluralism，its primitive nature and secondary nature.
