The starting point is the child who is cherished and held in "Sunday in Beijing", which extends to the relationship between adults and children. This relationship is reflected in two aspects. From a microscopic point of view, children are part of the continuation of their parents' lives, a cycle of inheritance. Children gradually grow into new adults. They never really die, and their genes and ideas will continue reincarnation.
From a macro point of view, in each era, the meaning of children to parents will change, and the way parents treat children will also change. This process of change is the second cycle of reincarnation. On Sundays in Beijing, the meaning of children to parents may be the hope of the family's labor force. In modern times, parents pay special attention to the education and training of children. Children may become tools for class change and personal display. With the emergence of incarnation technology, parents have strengthened their control over their children. At the same time, some Kochi parents have also realized the hidden dangers of excessive control. With the arrival of the post-human era, people will eventually return to the original attitude of natural stocking of children.
