[Analysis].
Everyone who has watched TV dramas knows that in ancient China, ministers often referred to the emperor as "Your Majesty". Maybe this is a familiar title in film and television dramas, and many people don't particularly care about it, or some people think that "Your Majesty" should mean "emperor" and "son of heaven".
In fact, "Your Majesty" originally did not refer to the emperor at all, so at the beginning, it was not even possible to talk about the meaning of "emperor" and "son of heaven".
In ancient times, when a courtier spoke to the Son of Heaven, he could not call the emperor directly, but he had to express extreme respect, so he had to call the waiters under the stage first and tell him, which was a bit similar to Mao De in "Qing Pingle", or Su Peisheng in "The Legend of Zhen Huan". The role of these waiters is to help pass things or help to pass the word.
From another point of view, we can also understand it this way: the emperor is the son of heaven, and the ministers are just ordinary mortals, in order to show their extreme respect for the emperor, the ministers do not dare to ask to see the emperor directly, but only dare to ask to see the waiter standing under the steps below the emperor. So at first, the four words "His Majesty the Emperor" were said together, but later I felt that the four words were a bit verbose, so I directly deleted the word "Emperor" in front of me, leaving only "Your Majesty".
Your Majesty: An honorific title for the Emperor. The original meaning is a waiter standing at the foot of the steps. "Majesty" refers to the steps of the imperial palace.
