Extended data:
The Qing government never cared about the country and the people, only cared about their own enjoyment, but didn't care about the lives of the people. Most of the Qing army was weak and afraid of death. As far as weapons are concerned, the Qing army, which entered the 20th century, has already achieved modernization in this respect, and even some troops have better weapons than the allied forces.
Most of the military expenditure in the Qing Dynasty was used by Cixi to do other things instead of developing the military. During Eight-Nation Alliance's war of aggression against China, most of the defenders fled, and Cixi also fled to Xi 'an, causing most of the officers and men guarding the city to abandon the city without firing a shot, resulting in the fall of Beijing.
It is worth noting that Yuan Shikai's new elite army of more than 10,000 Tianjin station did not participate in the whole war, and even watched the fire from the other side. The southern provinces also jointly signed a "Southeast Mutual Protection" treaty with the great powers, which turned the whole war into a contest between the imperial forces in Beijing and the great powers.
