《汉书·志·五行志中之下》
秦始皇帝刚即位时尚在幼年，朝政交给太后，太后与吕不韦以及穋毒通奸，封穋毒为长信侯，把太原郡作为穋毒的封国，宫室苑囿任他进出，为所欲为，朝政也由他决断。
秦始皇即位尚幼，委政太后，太后淫于吕不韦及嫪毐，封毐为长信侯，以太原郡为毐国，宫室苑囿自恣，政事断焉。
When Emperor Qin Shihuang was first crowned, he was still a minor, and his mother, the Empress Dowager, was in charge of the government. The Empress Dowager was having an affair with Lv Buwei and Lao Ai, and she conferred the title of the Marquis of Changxin on Lao Ai and gave him Taiyuan County as his fief. He was at liberty to go in and out of the palace and had access to Lady Ai's harem, and he also made all the government decisions.
