Did the introduction of a merit-based civil service lead ti decline in filial piety?

There is no conclusive evidence to suggest a direct relationship between the introduction of a merit-based civil service and a decline in filial piety in any particular society or culture. While the merit-based civil service emphasizes qualifications, skills, and competencies for government positions, filial piety is a cultural and social norm pertaining to respect and care for one's parents and elders.

In general, filial piety is influenced by various cultural, social, economic, and historical factors. Changes in filial piety over time can be attributed to broader societal shifts, changing family structures, modernization processes, and evolving social norms rather than simply being a consequence of a merit-based civil service system.
