《旧唐书·本纪·卷十九》
这年冬天极为寒冷，大街上积满了雪，士兵们入城的那天夜晚，严寒凛冽尤其厉害，遭到抢劫的百姓和官吏，冻僵之后死在地上，尸体盖满了地面。
是冬苦寒，九衢积雪，兵入之夜，寒冽尤剧，民吏剽剥之后，僵冻而死蔽地。
The winter of that year was unusually harsh. The streets were covered in snow. On the night the soldiers entered the city, the bitter cold was especially severe. People and officials who had been robbed froze to death and their corpses covered the ground.
