《宋史·列传·卷八十三》
雄州一带过去在上元节时都不燃灯赏玩，李允则在山上张灯结彩，派伶官表演歌舞，让人们彻夜游玩。
上元旧不燃灯，允则结彩山，聚优乐，使民夜纵游。
In the past, people in Xiongzhou did not light up lanterns and have fun during the Lantern Festival. Li Yunze hung lanterns and colored streamers on the mountain, and sent entertainers to perform singing and dancing, so that people can have fun all night.
