《史记·十二本纪·五帝本纪》
黄帝获得上天赐给的宝鼎，于是观测太阳的运行，用占卜用的蓍草推算历法，预知节气日辰。他任用风后、力牧、常先、大鸿等治理民众。
获宝鼎，迎日推策。举风后、力牧、常先、大鸿以治民。
Huang Di obtained the precious cauldron bestowed upon him by heaven, so he observed the movement of the sun, used divination grass to deduce the calendar, and predicted the solar terms and dates. He appointed Feng Hou, Li Mu, Chang Xian, Da Hong, and others to govern the people.
