（二十六）　是年有慶山始出。唐五行志曰。垂拱二年九月。雍州新豐縣有大風雷電震吼涌出一山。高二十丈。有池周三百畝。池有龍鳳之形禾麥之異。天后以為休應。故名曰慶山。

(26) In this year, Mount Qing first emerged. The "Treatise on the Five Elements" of the Tang History states: In the ninth month of the second year of Chuigong, in Xinfeng County of Yongzhou, amidst a great wind and roaring thunder and lightning, a mountain welled up from the ground. It was two hundred feet high, with a pond of three hundred mu around it; in the pond were the shapes of dragons and phoenixes and anomalous ears of grain and wheat. The Empress of Heaven took this as an auspicious sign, and therefore named it Mount Qing (Mount of Celebration).
