It was believed that the Tang Dynasty was a historical period with relatively few pandemics and little impact in the official history records. The reasons for this and the context and the living conditions of people during pandemics should be analysed in depth. This paper examined 49 pandemic outbreaks which seriously influenced on the society of the Tang Dynasty in terms of time and space distribution, historical features, correlation with other disasters, and regional distribution. The paper also analysed the measures taken by the government to deal with pandemics, including sending physicians and herbs, compensating the people, providing prescriptions, and burying dead bodies. This paper summarised the understanding of pandemics in the Tang Dynasty, such as the will of ghosts, the karma, the astrology and the contagion between the patients. It was found that the ways for the people at that time dealt with pandemics, included praying, offering sacrifices, asking for help from Monks and Taoist, and even moving to other safe places. It was also found the dead who were properly buried could give people psychological comfort.
