Can the Guangxu Emperor's successful transformation of the law save the Qing Dynasty? It depends on how to define the success of the variation.
In fact, the success of the change of law was not particularly important to the Guangxu Emperor, who only used the change to seize power. Once you have power, whether the change will continue is unknown.
Perhaps in the eyes of the Guangxu Emperor, the change of law is actually a process of re-integration of power, he wants to use the change of law to dismiss a group of old people, to use a group of new people, and whether the new people support the restoration is not important, the important thing is that the new people must completely and completely support the Guangxu Emperor. Once the Guangxu Emperor achieved this goal, what he considered to be a success.
As for how much the Fa has changed and how it has become, it may not be very important to the Guangxu Emperor.
To tell you the truth, I personally don't think that the Guangxu Emperor was a person with the ambition to restore the new, let alone how to restore the new. Compared with the previous Qing emperors, he had a personal experience of the backwardness and decline of the country. But the question is, which last-day monarch in the past dynasties did not understand it?
Learning from the West, in the era when the Guangxu Emperor lived, it was the most fashionable word, it was a big banner, and with it standing, a large group of supporters could be gathered around, which was the ambition of the Guangxu Emperor.
But he did not realize that his own father, Empress Dowager Cixi, knew better than him what restoration was, and he knew better than how to restore the new, more securely and efficiently. Therefore, the people who really understand and will restore the new are on Cixi's side, and this group of people happens to be the ruling faction that has been doing foreign affairs for decades. They deeply understood that if they wanted to make Daqing stronger, Cixi might not be able to do it, but if they wanted Daqing to die, they could just turn to the Guangxu Emperor.
Therefore, no one with real ability and real power will side with the Guangxu Emperor, and the so-called change of the Guangxu Emperor will inevitably fail. If the Guangxu Emperor really succeeded in seizing power by changing the law, it would mean that the people who could really do things had already been killed. Relying on people like Kang Youwei, the Qing Dynasty is estimated to be not far from death.
