Origin and Story of 夜以继日

During the Western Zhou Dynasty, King Wu passed away not long after he conquered the Shang Dynasty. His son, King Cheng (Ji Song), ascended the throne at the age of 13. All major state affairs were entrusted to his uncle, the Duke of Zhou (Ji Dan), who acted as regent.

To ensure the stability of the Western Zhou regime, the Duke of Zhou worked tirelessly day and night. He successfully put down a rebellion orchestrated by his own brothers who had conspired with Wu Geng, the son of the last Shang king.

The Duke of Zhou devoted himself to assisting in governance, never complaining about the immense workload.
