About Lao Ai
Lived 250 BC – 238 BC (aged 11–12). Lao Ai was a politician.
Lao Ai (; died 238 BCE) was an imposter eunuch and official of the State of Qin during the late Warring States period. Allegedly falsifying his castration in order to gain entry into the court of Qin, he became the favorite of Queen Dowager Zhao, the mother of Qin Shi Huang, later the First Emperor of China. He was enfeoffed as Marquis of Changxin (長信侯). After a conspiracy to incite rebellion was uncovered, he was executed by Qin Shi Huang.
Since the conspiracy and downfall of Lao Ai, his sexual misdeeds have become a fixture in the traditional moralizing discourse of intellectuals in imperial China, and his very surname and style name, which meant "lustful misdeed" in Old Chinese, has become a byword for "fornicators" in the classical Chinese language.
Biography According to Sima Qian's Records of the Grand Historian, Lao Ai had a giant penis, being of such size that it could be used as an axle for a wooden carriage. This ability drew the attention of Lü Buwei, who was having an affair with Queen Dowager Zhao, mother to King Zheng of Qin (later Qin Shi Huang), and Lü plotted to make use of Lao's sexual prowess to ingratiate himself with the Queen Dowager.
Historicity The historicity of Lao Ai has been doubted by modern historians, who consider that Confucian ideologues, who were in favor with the Han court during the composition of the Records of the Grand Historian, had the ulterior motive of portraying Qin Shi Huang, a foe of Confucians who had ordered their mass execution in 212 BCE, as a bastard. Supporters of this theory point out that Lao Ai's name appears etymologically fanciful: the characters used to write Lao Ai literally mean "lustful misdeed" in Old Chinese, and that his defining characteristic, his large penis (in Chinese ), can also be taken to mean "great conspiracy". Given that Sima Qian, author of the historical work that canonized this traditional account of Lao Ai, was himself subject to the punishment of castration some years before, skeptically minded historians believe that the story of Lao Ai is meant to be understood allegorically, as a "personified phallus" who represented "a basic threat to the transmission of the imperial bloodline and hence the purity of the 'united cosmos'".
The story of Lao Ai was also told by Yu Shaoyu , the 16th-century author of Chronicles of Many States During the Age of Spring and Fall, the length of which was nearly tripled by Feng Menglong (1574–1646), after which the book was then known as Chronicles of the Eastern Zhou Kingdoms.
