Pre-Qin (先秦) Chinese society is full of ideological dialectics and challenges, especially the intense diversity from Zhou Dynasty (周朝) to the Chungqiu (春秋) and the Warring States Period (戰國). As a new head of the pledged tribes of the Yellow River region, Zhou Dynasty has been constructed as a patriarchal society related to Zhou and its ethical system for subsistence and development, in accordance with the culture character of Zhou civilization and ideological context. Among the ethical system, Qin-Qin (親親) (Loving One's Relatives) the thought has became the key force and the primary human ethics which in the future will receive a direct critique by Mohist. This article explores the fundamental conflict between Mozi (墨子) ethics and the Qin-Qin idea through the alteration of both ethics ideology and the opposition relations, and discusses the main reasons that cause them conflict. This research demonstrates that only the advantage of supreme values and the Mozi special growth background and disposition are key aspects.
