Final answer:
Kaobawa likely began the work himself to demonstrate leadership by example, reflecting cultural narratives where leaders work with their subordinates to inspire effort and commitment.
Step-by-step explanation:
In preparing the central plaza for the feast, Kaobawa likely began the work himself to set an example of diligence and commitment. This reflects a common theme in historical and cultural narratives where leaders engage in manual labor alongside their subordinates to inspire solidarity and ensure the high standards of the work. Similar instances can be seen in the texts provided, such as sage-king Yu who carried his tools himself, working tirelessly to channel the Yellow River, or the elite Kano School involving apprentices, junior artists, and the master Kano Eitoku himself, to complete commissions for important daimyo like Oda Nobunaga and Toyotomi Hideyoshi. These examples show leaders and masters directly contributing to significant projects, emphasizing the importance of shared effort and the personal commitment of leaders to their causes or responsibilities.
