What are some incidents in history where people "pretended to be cool" but were slapped in the face?

There is a saying on the Internet that goes like this: "Don't pretend to be cool, or you will be struck by lightning if you pretend to be cool." And looking at the figures who have left their names in history, they are also on the list of pretenders. Use Strength and courage fulfill the accuracy of this sentence. As the saying goes, don't talk too much. It's like pouring pure water into a cup. The part that is in the cup is drinkable, but what comes out is not drinking water. History is a moment to witness miracles, and it is also the witness that slaps the loudest in the face. 1. Liu Yong, a figure in the poetry world of the Song Dynasty

This is a legendary figure in the world of poetry. He can't get along in the officialdom, but he can still get along well in the romantic world. Every time he produces a poem, he will be sought after by everyone. It can be said that it has reached this point: I don’t want to wear silk, but I want to be with Brother Liu Qi; I don’t want to be called by the king, I want to be called by Liu Qiming; I don’t want a thousand golds, I want to win Liu Qi’s heart; I don’t want to see gods, I want to know Liu Qi Seven Faces?

Such an irresistible talent makes Liu Yong’s life as bright as the cheating male protagonist. But his achievements in becoming famous at a young age also caused him to show off and get slapped in the face. It was the imperial examination of a certain year. Liu Yong hummed: "I have a little donkey. He wrote "Longevity" with a wave of his hand, directly defining his own unlimited future, which is Liu Yong's imagination. In the middle: The face of the sky is so close, I am sure to be the best. When I am dead, I am waiting to come back to congratulate you. ?

However, the result was that Liu Yong failed the exam, and the once complacent Ding Bing came out on top and became a big joke, slapping himself in the face. 2. My son of Kangxi will definitely not have a falling out

Throughout the ages, seizing the heir has been a turbulent domestic drama. Who can guarantee that it will not happen after his death? However, Kangxi dared to swear and speak righteously, but it was just a problem for his sons. Seeing him take it at his fingertips, the garden would be full of peach blossoms. Looking back at the past, Kangxi smiled coldly. It was just a matter of dealing with the affairs after his death. You, Tang Taizong, actually caused such a big turmoil. It was so useless. Let's see how Kangxi managed to create a peaceful and prosperous age in the world. However, the ending was shocking. After Kangxi, the most cruel incident of seizing the legitimate son occurred that shocked history. It was known in history as "Nine Sons Seizing the legitimate son". This pretentious incident was a slap in the face.
