《新唐书·列传·卷六十三》
城墙有个角落崩塌了，多次修好后又塌了，李嗣业在那里祷告，有条白龙出现了，因此在那里建祠祭祀，城墙就不塌了。汉代耿恭的旧井长期干涸，他祈祷以后，泉水又有了。
城一隅阤，屡筑辄坏，嗣业祝之，有白龙见，因其处蕝祠以祭，城遂不坏，汉耿恭故井久涸，祷已，泉复出。
A corner of the city wall collapsed, and it was repaired many times and then collapsed again. Li Siye prayed there, and a white dragon appeared, so he built a temple there to worship it, and the city wall would no longer collapse. Geng Gong's old well in the Han Dynasty had been dry for a long time. After he prayed, the spring water came out again.
