Abstract: According to Habermas, in modern society, due to the separation of the economic system and the administrative system from the living world, they have gradually become a force to interfere and control the living world that was originally free, open to communication, and full of understanding and trust, and have led the world to "colonization". In the medical field, this "colonization" is mainly manifested by the alienation of the doctor-patient relationship, that is, excessive economicization, technicalization, legalization and other relationships have become the dominant relationship between doctors and patients. The original negotiation, dialogue,understanding, mutual agreement and humanistic doctor-patient relationship have been obscured or abandoned, which led to the
severe consequences of doctor-patient tension and even conflict. Therefore, it is necessary to restore the doctor-patient relationship to
healthy and reasonable state through the stimulation of the normal functions of the three systems of life, culture, society and
personality, so as to protect the patients' live and medical rights.

Key words: living world, colonization, alienation, healthy doctor-patient relationship
