《淮南子·天文训》
四守则主管奖赏惩罚。太微主管朱雀，紫微宫持北斗而左旋，每天运行一度而环绕周天。
四宫者，所以为司赏罚。太微者主朱雀。紫宫执斗而左旋，日行一度，以周于天。
The Four Guards will supervise the rewards and punishments. Taiwei acts as the vermilion bird, while Ziwei Palace holds the North Star and spins to the left, traveling by 1 degree each day and revolving around the entire sky.
