During the Spring and Autumn period, Confucius, a great philosopher, hoped that rulers would adopt his benevolent political ideas. While he served in the State of Lu, the Duke of Lu was heavily influenced by the powerful Ji clan, which hindered Confucius's ability to implement his vision.

Feeling his talents were not fully appreciated, Confucius sighed, 'If anyone were to employ me, I could achieve something in a month, and great success in three years.' However, the Duke of Lu did not give him significant responsibilities.

Confucius held the belief, 'When the state is governed by the Way, one should serve; when the state is not governed by the Way, one should withdraw.' Therefore, embracing the principle of 'waiting for a good price to sell' (善贾而沽), meaning to bide his time until he found a ruler who would truly recognize and value his abilities, he set out to travel among various states.
