《三国志·魏书·少帝纪》
天子又下令特许晋王戴只有皇帝戴的前后有十二根玉串的冠冕，使用天子的旗帜，出入有御林军沿途警卫并禁止路人通行，乘坐皇帝专用的六匹马拉的金根车，后面跟随配以青、白、红、黑、黄五种颜色的五辆从车。又特许晋王宫殿中可以设置悬挂钟磬的木架，可以演奏皇宫中的八佾乐舞，设置钟虡宫县。
又命晋王冕十有二旒，建天子旌旗，出警入跸，乘金根车、六马，备五时副车，置旄头云罕，乐舞八佾，设钟虡宫县。
The emperor also issued a special decree to allow the King of Jin to wear a crown with twelve jade strings in front and behind, which was only worn by the emperor. He could use the emperor's flags, have Imperial Guards on duty along the way, and prohibit pedestrians from passing by. He could ride in a golden carriage pulled by six horses, which was used exclusively by the emperor, and be followed by five escorting carriages in green, white, red, black, and yellow. The King of Jin was also specially allowed to set up a wooden frame to hang bells and chimes in his palace, where he could perform the eight-row dance music of the imperial palace, and set up a clock and bell county.
