《史记·十二本纪·孝武本纪》
天子既已听了公孙卿和方士的话，黄帝以上的封禅，都会引来一些能与神仙相通的怪异之像，所以想仿效黄帝接见神仙人蓬莱方士之法，让自己的德行高于世俗，与九皇相媲美，又采用儒家的说法来文饰外表。
天子既闻公孙卿及方士之言，黄帝以上封禅，皆致怪物与神通，欲放黄帝以尝接神仙人蓬莱士，高世比德于九皇，而颇采儒术以文之。
The Son of Heaven has listened to Gongsun Qing and the warlock, the ceremonies of the Yellow Emperor and the above, will all attract some weird images that can communicate with immortals, so he wants to imitate the Yellow Emperor to meet the immortal Penglai warlock, so that his morality is higher than secular, and comparable to the Nine Emperors. And he uses the Confucianism to decorate the appearance.
