五年二月。詔嘉州峨眉山沙門茂貞入見。上賜以詩。館於景德寺。舒王元偁夢青衣童持書以授中使。足蹈黃雲隱隱而沒。王以問師。答曰。將有儲嗣降孕之慶。未幾仁宗生○初樂史留守西京。夢天帝召謂曰。世主求嗣吾為擇之。少選一人至。帝曰。中原求嗣汝往勿辭。遂唯而去。旁侍者曰。此南岳赤脚李仙也。明年仁宗生（張師正括異記）。

In the fifth year, in the second month, an imperial decree summoned the monk Maozhen of Mount Emei in Jiazhou for an audience. The Emperor granted him a poem and lodged him in Jingde Temple. Prince of Shu Yuancheng dreamed of a blue-clad youth holding a letter, handing it to a palace envoy, stepping on yellow clouds and gradually vanishing. The Prince asked the Master about it, and he replied: 'There will be the joyous event of the conception of an heir apparent.' Soon after, Renzong was born. / Earlier, when Yue Shi was governor of the Western Capital, he dreamed that the Celestial Emperor summoned him and said: 'The ruler of the world seeks an heir; I will select one for him.' After a short while, a person arrived, and the Emperor said: 'The Central Plains seeks an heir; you go, do not decline.' He then assented and departed. An attendant at his side said: 'This is the Barefoot Immortal Li of the Southern Marchmount.' The next year, Renzong was born. (Zhang Shizheng's Kuoyi ji.)
