A girl mesmerised two ducklings to sleep with her own lullaby in China.

Video filmed in Xi'an City in Shaanxi Province on June 5 shows a 5-year-old girl softly humming her self-composed hypnotic tune, with two ducklings gradually lowering their guard, closing their eyes slowly, and eventually lying down peacefully, drifting into sweet dreams.

According to Ms. Tong, the girl's mother, they had brought the ducklings home just two days prior. That evening, before bedtime, the child wanted to put the ducklings to sleep first, unexpectedly succeeding. Normally, the ducklings sleep lying down, and Ms. Tong found her daughter's actions quite miraculous.

Animal experts suggest that the girl's humming likely produced a soothing rhythm and tone that comforted the ducklings. Animals are typically sensitive to sounds and rhythms, and this gentle music may have helped relax the ducklings and induce sleep.

近日，陕西西安，一位小女孩用自编催眠曲哄两只小鸭子入睡。
视频显示，小女孩轻声哼唱着自编的催眠曲，温柔的声音充满节奏感，仿佛拥有一种魔力，能让周围的一切都安静下来。在她的歌声中，两只小鸭子逐渐放下了警惕，慢慢闭上了眼睛，最终仰躺着进入了甜美的梦乡。它们的睡姿十分可爱，让人忍不住想去摸摸它们柔软的羽毛。
据女孩妈妈童女士介绍，女儿今年五岁，小鸭子带回家里才两天，当天晚上孩子睡觉前就想着先把小鸭子哄睡了，没想到竟然真得哄睡了，平常小鸭子都是趴着睡的，对于孩子的这种行为自己也很觉得很神奇。
据动物专家介绍，小女孩的哼唱可能产生了一种舒缓的节奏和音调，这对小鸭子而言具有安抚作用。动物们通常对声音和节奏敏感，这种轻柔的音乐可能帮助小鸭子放松并入睡。动物具有天生的警觉性，但在感受到安全和舒适的环境时，它们会放松警惕。小女孩的温柔声音和轻柔的动作可能营造了一个让小鸭子感到安全的环境，从而使其更容易入睡。另外，人类与动物之间的互动可以产生深厚的情感联系。小女孩通过与小鸭子的亲密接触和安抚，增进了彼此的信任感，这种信任感有助于小鸭子放松并进入睡眠状态。
