In response to the calamity of heaven, Northern Emperor Xuanwu passed through East Kunlun and passed through Houwu Mountain. He was forced by the severe cold and left behind the Xuanming Staff. The rod of hell entered the soil and took root, transforming into a yarrow. Folks use yarrow for divination, and yarrow is also known as 'Siming grass'. Legend has it that after a thousand years of cultivation, the root of Simingcao gradually turns purple and is protected by a divine turtle. ——"Book of Destiny·Volume of the Gods"
