Abstract: In Dai Zhen's ethics study, Fen Li means the distinction and integration among human beings, the core of which is the general "desires". In order to clarify the Fen Li, he adopted the way of Yi Qing Xie Qing. However, there is a possibility that this method may ignore others' "desire" claims in practice, so we still need to optimize it. Later scholars added Xin Zhi, an intellectual concept, to Xie Qing and this paper introduces the concepts of "don't do to others what they don't want" and dialogue. On the one hand, it elevates the other to the level of non-assimilation; on the other hand, it presents others' "desires" through dialogue, which can further advance the Xie Qing on the path of clarifying Fen Li.

Key words: Fen Li, Xie Qing, others, dialogue
