《太平广记·卷十八·神仙十八》
当时汉武帝想给朝里选拔太中大夫，就在石渠署召见扬雄、王褒等文人，命他们作赋和颂，我才从他们那里学到了箴论。
汉武帝求太中大夫，遂在石渠署见扬雄、王褒等赋颂，始晓箴论。
At that time, Emperor Wu of the Han Dynasty wanted to select Taizhong大夫 for the imperial court, so he summoned scholars such as Yang Xiong and Wang Bao to the Shiqu Office and ordered them to make essays and odes. I learned the theory of admonition from them.
