Imagine trying to study for exams while a booming ‘Guangchangwu’ (square dance) playlist rattles your windows! 🤯 That’s exactly what sparked a clash between Beijing’s passionate dancers and frustrated residents in the Jinrongjie area—until a high-tech fix turned the volume down without killing the vibe.
For years, the square buzzed with rhythmic moves and blasting speakers every night. But after noise complaints flooded the Beijing 12345 Citizen Hotline—including from students struggling to focus—officials got creative. Enter directional sound wave technology, which beams music only to the dance zone, like a sonic spotlight! 🎯🔊
‘It’s like magic,’ one resident told CGTN’s documentary Hotline Beijing. ‘The music stops at the edge of the square!’ Scientists, local leaders, and the community teamed up to test the system, balancing cultural expression and neighborhood peace. Now, dancers keep grooving, kids ace homework, and everyone’s hitting refresh on community harmony. 💃📚✨
