Which western power wanted to bully the Qing dynasty, but it was "humiliated" by the Qing dynasty, which led to the government's stepping down?

At that time, Italy wanted to bully the Qing dynasty, but it was humiliated by the Qing dynasty and directly let Italy's head step down. Italy has long seen the weakness of the Qing dynasty and wanted to share some sweetness, but I didn't expect that although the Qing dynasty was incompetent at that time, it didn't pay attention to Italy. Italy threatened the Qing dynasty with war at that time, but the Qing dynasty was not afraid, but actively responded.

At that time, Italy tried to attack France, but unfortunately failed in the war. Then they tried to attack Ethiopia, but they failed. After two failures, Italy finally shifted its target and began to invade the East. At that time, the Italian government submitted the idea of renting Sanmen Bay as a naval base to the Premier Yamen of the Qing Dynasty. But I didn't expect his idea to be rejected by the Qing government.

At that time, the Qing government returned the paper submitted by Italy without even reading it. This move made Italy very angry when it was known. At that time, the Italians thought that the Qing government was just weak in the outside world, and China would give in if it was frightened by its incompetence once.

So at that time, Italy sent three warships to demonstrate to the Qing Dynasty at Sanmenwan Port. The Qing dynasty didn't care about this demonstration in Italy. Italy became angry from embarrassment and directly issued an ultimatum to the Qing dynasty, forcing the Qing government to agree to Italy's demands or go to war. But when Italy finished this ultimatum, it regretted it, because Italy was not fully prepared at that time. The Qing government at that time was not as weak and incompetent as we thought. At that time, the Qing government not only rejected Italy verbally, but also actively responded. This put Italy in a very embarrassing situation, so the Italian head of state had to step down in order to save Italy's losses.
