Is Wei Guifei dead? Why did you commit suicide, drink poisonous wine, and fall into the emperor's arms to plead for Chun Er?

Because Princess Chun Er stole military symbols and mobilized the guards, it almost put Chang 'an in danger. Later, when the princess came back, the emperor punished Princess Chun and put her in prison for execution. Wei Guifei was anxious to save her son and drank poisoned wine in front of the emperor. Begging the emperor to intercede for Chunfei, the emperor was moved and the imperial concubine died in his arms.
