Why did the living take care of dead ancestors?

The living took care of their dead ancestors as a way to honor and show respect for them, believing that this practice would ensure their ancestors' spirits remained at peace and could provide protection or guidance to the living. Rituals such as cleaning graves, making offerings, and conducting ceremonies were seen as ways to maintain familial bonds and cultural traditions. Additionally, caring for ancestors reinforced social cohesion and a sense of identity within communities. This practice reflects a deep respect for lineage and the idea that the past continues to influence the present.
