Li Yi
In Li Yi's youth, he was said to be shy and a poor speaker, and (falsely) considered by others to be unintelligent. Later, during the reigns of Emperor Muzong's sons Emperor Wenzong and Emperor Wuzong, Li Yi was said to try to hide himself from the political scene, and rarely spoke anything at all. When the emperors visited the imperial princes' residences, known as the Sixteen Mansions, they would, as a game, try to get Li Yi to speak, and they referred to him as "Uncle Guang." It was said that Emperor Wuzong, who had an outgoing personality, particularly disrespected Li Yi.
