"The emperor is not the same as the one dressed in white", this is a classic saying of Liu Xiu, Emperor Guangwu of the Eastern Han Dynasty.

What Liu Xiu meant, analyzed based on the situation at the time, was of course that when he became an emperor, he had to talk about the overall situation and the laws and disciplines, instead of being like the common people in the past. In a word, when you become a leader, you should be subject to more constraints, bear greater responsibilities, and should not be too casual or willful in doing things. From this, we can see that Emperor Guangwu was generous, responsible, and knowledgeable about talents, especially in terms of unifying power and responsibilities. His views were very advanced at the time.
