Based on the four reincarnations of a small contractor (contractor, dog, pig, and cow), it describes the "hard work" of the contemporary lower class people - it is not because of bad fate, but because they are pushed by the times, desires, and human feelings; the species in each life corresponds to The obsession and destiny of the previous life, the humbleness of the dog corresponds to the dependence on others in the previous life, the survival of the pig corresponds to the struggle to survive in the previous life, and the hard work of the cow corresponds to the desperate running of the previous life. Step by step, the hostility fades away and the true heart is faced.
The awakening of the fifth-generation vegetative person is "redemption": it is not the end of reincarnation, but the real beginning of living - letting go of obsessions, seeing the suffering in the world, and taking in the warmth of the world, breaking the shackles of "working is living", and interpreting "the essence of living is experience, perception, and the cherishment and response to beauty."
