The subject discussed in this paper is how to make use of China's traditional wisdom of death and the viewpoint of life and death permeability to help modern people to free from anxiety and fright of death. The paper holds themselves these opinions: (l) Modern life quality, is better than the traditional one, but in the respect of death quality, worse. Modern people are more frightened of death than traditional people. (2) Death is a very big “dark hole”, without issue. It can only be inferred and imagined; and it is the biggest and deepest tragedy of human beings. (3) China's traditional wisdom of death can be divided into two categories: one is the wisdom which servers life and death; the other is the one that links them both. Both wisdoms have their own pragmatic value. (4) The basis on which to construct a scientific and feasible viewpoint of life and death is to understand and practice the idea of life and death permeability.
