Since Buddhism was introduced into the Central Plains during the Han Dynasty, it has become one of the important components of the social and religious structure of China. In different social stages, the distribution of buddhist temples can reflect the characteristics of the social structure of a region. The Han Monasteries originated in Xuhuai, Pengcheng in the Han Dynasty. The present northern Jiangsu is the earliest birthplace of Buddhism in Jiangsu. Liu Ying, the king of Chu who ruled Xuzhou in the Han Dynasty, was the earliest ruler who believed in Buddhism in history. In recent years, under the relaxed social environment, the protestant population grew rapidly, and the rural area was relatively remote, which caused the government departments to understand the current situation and development direction of religion in northern Jiangsu in a timely mann er. The investigation on the status quo of Buddhism belief in Xuzhou shows the interaction between religion and society, which can be used for reference by the government and religious departments, and has great practical significance and social value.
