Besides, Brother Hong Yong. Because of doubts about Li Hong in TV series, Zhen Xuan adopted Hong Yong to Guo Ziyu. For the audience, this plot is well set, which can be regarded as a comfort to Guo Ziyu and a reunion of father and son. However, in real history, Hong Yong, the sixth brother of Yongzheng, was indeed adopted to the name of King Guo Jun, but he was not a child of Yongzheng, but a child of Yongzheng and Ganfei.
Ganlong loves this little brother very much. It happened that King Guo Jun had no children and no one inherited his title, so he put Hong Jun in the name of King Guo Jun, and Hong Jun inherited the title of King Guo Jun at a young age.
And Nian Gengyao. Nian Gengyao made a lot of efforts for the throne of Yongzheng in history, but Yongzheng dealt with him because his arrogance touched the bottom line of Yongzheng. In the TV series, Nian Gengyao's sister Nian Shi was indeed the concubine of Yongzheng, but later I learned that Yongzheng used their brother and sister. But according to real historical records, Yongzheng really loved Nian Gengyao's sister Nian Gengyao, and even suspended the punishment for Nian Gengyao because of Nian Gengyao.
Yongzheng was really good to his seventeenth brother in history. When Jiuzi was in power, Guo Ziyu County was a child and didn't participate in it, so there was no threat to Yongzheng. After Yongzheng ascended the throne, none of his brothers came to a good end. After some treatment, there is not much left. Later, Yongzheng trusted Brother Thirteen the most, and was very sad after his death. He took Wang Yunli, the king of Guo Xian County, as his relatives and trusted brother.
Another example is that the eunuch around Yongzheng is Su Peisheng, and the relationship between Yongzheng and his mother Wu Yashi is really unfamiliar. TV plays are just fictional entertainment based on history, so don't take them too seriously.
