What are your thoughts after watching the opera Le Nozze di Figaro?

As the curtain opens, Rosina is lamenting the neglect she has received from her husband. She prayed sadly: "O God of love, please have mercy on me"! Susanna enters the scene, followed by Figaro, and the three of them discuss a plan to punish the count together, which will not only make the count change his mind, but also protect their own happiness. This plan is divided into three steps: first forge a whistleblower note to warn the count that his wife is about to date her lover, teach him to pay more attention to the actions of the visitor, and make him jealous. On the other hand, Cherubino is dressed as a girl and serves as Susanna's substitute to have a tryst with the count in the garden at night. In the end it was the countess who went to the garden to "catch an adulterer", making the count feel ashamed. The valet Cherubino sang one of the most outstanding arias in the play at this time, "Do you know what love is?": "Do you know what love is? Who of you understands my feelings? I want to Tell you all this. I can’t explain this wonderful feeling. I just feel my heart is churning. Sometimes I am happy, sometimes I am sad, and love burns in my chest..." This lovely song touched the countess. and Suzanne. They told Cherubino Figaro's plan and asked him to do a favor before leaving. Of course, Cherubino did not object, because this way he could attend Susanna's wedding and get close to Barbarina, the gardener's daughter. At this time, Susanna brought a set of beautiful women's skirts and dressed Cherubino, and the three of them followed the plan. Soon, the count came to the door of the lady's room, knocked on the door and asked to enter. Rosina asked Cherubino to hide in the bedroom next door, and Suzanne also hid behind the curtains. Rosina opened the door, and sure enough, it was her husband, Almaviva, shaking with rage holding a tell-all letter in his hand. He asked the lady: "Why did it take so long to open the door? Is there a man hiding here?" The lady deliberately replied: "No." The count didn't believe it. He pushed the bedroom door, but it couldn't be pushed open. It turned out that It was Cherubino who locked it from the inside. The furious Earl said he was going to find tools to split the door open. The moment the count and lady walked away, Cherubino ran out of the bedroom. Suzanne asked him to escape quickly, but all the doors in the house were closed, so they had to open the balcony door. Rubino was heartbroken and jumped down. Suzanne ran into the bedroom and locked the door from the inside. The count came back with his wife in hand, holding a big hammer and a pair of pliers in his hands, and angrily slammed the door. However, when the door slid open, he was really surprised: the person inside was Susanna. The countess breathed a sigh of relief, but she in turn accused the count of being too distrustful. The count was embarrassed and quickly apologized to his wife. The gardener Antonio hurried over and reported to his wife that a man had just jumped from her balcony and knocked down a flower pot. After hearing this, the count became suspicious again. Fortunately, Figaro arrived in time and said that he had just jumped. He was the one who went down. He wanted to meet his fiancée in the lady's room, but he was embarrassed when the count saw him, so he ran away. As he spoke, he pretended to be limping, saying that he had sprained his foot just now. At this time, Marcellina, doctor Bartolo, and music teacher Basilio came, and they announced proudly: Figaro had not paid back the money, and now he must fulfill his agreement: marry Marcellina. The witness was the doctor Bartolo. This news made everyone present have different expressions: the proud Marcellina and the doctor, the gloating Basilio and the count, the pitiful Susanna, the sympathetic countess, the overwhelmed Figaro--Sing Play a ridiculous septet.
