Is it a joke that Liu Pengzi proclaimed himself emperor and Liu Pengzi proclaimed himself emperor?

Liu Pengzi was originally a descendant of Liu Bang, the grandson of Emperor Gaozu. Liu Zhang's grandfather, Liu Xian, was made a marquis of Wu in the Han and Yuan Dynasties. Liu Zhang's father, Liu Mengcheng, attacked this title, and then met Wang Mang to usurp the government. His father's title was not, so Liu Penzi began to be an ordinary person.

After the Red Eyebrow Army Uprising, Liu Pengzi and his two brothers, Liu Mao and Gong Liu, stayed in the army after passing through the county where Liu Pengzi lived. Liu Penzi's brother Gong Liu himself lived up to expectations. He has read classics such as Shangshu since he was a child, so he knows some truth and righteousness. Later, Liu Pengzi followed Fan Chong to take refuge in the former emperor Liu Xuan, and Liu Xuan named Gong Liu Hou. Liu Pengzi also has the title of Marquis. After Wang Mang usurped power, the Marquis disappeared, and then Gong Liu won the title of Marquis for taking refuge in Liu Xuan. Later, because Gong Liu was familiar with some texts and classics, he was appointed as an assistant. Liu Penzi, who had never read a book, was only responsible for mowing grass and feeding cattle in the army. Later, the Red Eyebrow Army uprising needed a justified rhetoric, so Fan Chong adopted Wang Fang's suggestion and made Liu Penzi, who was easy to control, emperor, with the aim of "making the imperial clan of the Han Dynasty emperor and commanding the world". So Liu Penzi sat on the throne and was called Jianshi Emperor.

Later, Liu Xiu and the Red Eyebrow Army fought a decisive battle, and the Red Eyebrow Army was defeated. Liu Pengzi surrendered and was escorted to Luoyang. Later, because Liu Penzi was blind, Liu Xiu used Xingyang's official land rent to support Liu Penzi.
