Why did Guangxu call Cixi his biological father in "The Magic Chef Little Fugui"?

In fact, Guangxu called Cixi "dad"

Every time Emperor Guangxu greeted the Empress Dowager Cixi, he would say "Blessed dad!" A generation of emperors repeatedly claimed to call women Yehenala is the "biological father". Although it sounds ridiculous, it is an ironclad historical fact.

Through the "Xinyou Coup" (1861), Cixi began the infamous behind-the-curtain administration. Her power was higher than that of Emperor Guangxu, and she actually occupied the high position of the Supreme Emperor. In the history of Chinese feudal society, only the emperor's father was worthy of the high position of emperor. Since Cixi regarded herself as the Supreme Emperor, she liked the emperor to call her by a man's name, and of course there was nothing more appropriate than calling her "Dad".

Emperor Guangxu was not born to Cixi, but to Cixi’s sister. Cixi once said: "My sister's son is just like my biological son." Adding the word "dear" before "father" not only appeals to the ears, but also conceals the suspicion of not being a relative.
