Psychological hotline is an important part of crisis intervention. Because of its timeliness，anonymity and convenience，it plays a major role in psychological crisis intervention. In 2008，the National Health Bureau for Disease Control and Prevention attached importance to the psychological assistance hotline in China，and began to promote the construction and standardized development of psychological assistance hotline in various regions. The main task is to pilot first，explore experience，and gradually promote. It will play an important role in psychological assistance in the prevention and control of novel coronavirus epidemic in 2020，with the climax of building a hotline. At the same time，it is also necessary to solve the key problems such as how to arrange the construction of psychological assistance hotline，how to standardize the management hotline，how to promote standardized services，how to do a good job in peacetime and wartime，how to reserve psychological assistance teams，and how to make the psychological assistance hotline develop rapidly. Taking the development of Beijing psychological assistance hotline as an example，the three major factors that affect the hotline service are service ability，management ability and financial support. In the future，it is necessary to further build a Beijing psychological assistance hotline network，establish a scientific and unified management model，strengthen the hotline service capacity，strengthen the construction of information systems and platforms，do a good job in publicity and promotion，and establish an expert committee.
