《资治通鉴·唐纪·唐纪二十七》
他们有时在一起谈论、一起赋诗，有时饮酒，有时玩博戏下围棋，有时策马纵犬外出打猎，有时手持丝竹乐器吹拉弹唱；李成器擅长吹奏笛子，李范擅长弹奏琵琶，他们都曾和玄宗在一起轮流演奏。
或讲论赋诗，间以饮酒、博弈、游猎，或自执丝竹；成器善笛，范善琵琶，与上共奏之。
Sometimes, they would converse together and compose verse, and sometimes drink, play board games and Go, or mount their horses, unleash their dogs, and go hunting, and sometimes hold strings and wind instruments and play and sing together. Li Chengqi was skilled at playing the flute, and Li Fan was skilled at playing the pipa, and they would each take turns playing together with Emperor Xuanzong.
