Yale students turned a Zhangjiajie mountain escalator into a moving concert stage. Singing "Molihua," or "Jasmine Flower," a beloved Chinese folk song, their voices echoed past the cliffs of Tianmen Mountain in central China's Hunan Province. 

Tourists paused, turned back, and raised their phones, capturing a touching moment when music met the mountains – and when young voices from the United States and China connected through a song.
