Based on certain things,such as Edward Taylor’s animatism theory,Frazer’s theory regard-ing the primitive magical thoughts,Gennep’s classic theories on Anthropology in his book Les Rites De Passage,the descriptions about abdication system in ancient books and records and the analysis regarding the age issue in The Book of History,we could reveal the truth that instead of being a result of moraliza-tion,it is the development of the society that finally makes people stop letting the untended elders die a-lone,instead,they would take care of the elders,and let their lives come to a natural end.When it comes to the late Shang and early Zhou Dynasties,the elders’lone death custom is no longer popular,people started to invest more time and energy to care for the elders.But before that,the elders’lone death custom is re-garded as a way that people shows their respect to the elders.
