《资治通鉴·唐纪·唐纪三十》
玄宗登临五凤楼设宴，观看的人十分拥挤喧闹，以至宴乐也无法演奏，金吾卫兵像下雨般挥动白棍，但也无法遏制人群，玄宗十分忧愁。
上御五凤楼酺宴，观者喧隘，乐不得奏，金吾白梃如雨，不能遏；上患之。
Emperor Xuanzong ascended the Wufeng Tower to hold a banquet. The crowd was so crowded and noisy that it was impossible to play the banquet music. The guards of Jinwuwei waved white sticks like rain, but they could not curb the crowd. Emperor Xuanzong was very worried.
