Abstract: To answer the questions of life and death, Zhuangzi and the Buddha responded by precious knowledge. This comparison of the thought of life and death involves many aspects, and the most fundamental issues are intermittent life and death, the existence of a constant subject, the transcendence and the ethical value of life and death. Zhuang Zi and Buddhism believe that death is not the end, and there is no constant subject. There is a similarity in the understanding of intermittent life and death and the existence of immutable subjects; Zhuang Zi did not have a clear and systematic explanation, which meant that the two had differences in transcending paths and ethical values. In comparison, Buddhism, with the idea of "get rid of life and death" has prosperous thoughts about life and death, which can make up for the shortcomings of Zhuang Zi's theory. By comparing those two theories, we can not only see the development of the theory of life and death in China, but also the necessity of the doctrine of Buddhism spreading.
