Through a unique database on daily activities of municipal party secretaries, we find that they spend a significant part of their work time on political and propaganda activities, including organizing various meetings to promote the central government's spirit ideology.

This is more evident among younger, well-educated politicians due to age-based promotion restrictions. Our study may shed light on how the Communist Party of China balancing economic development and political loyalty when selecting officials.
