Introduction: On a live broadcast program for street interviews, I met a ragged Tang Yao. The host's eyes lit up, and he was about to step up to the interview, but suddenly saw Tang Yao lightly strumming the guitar, playing a melodious sound. The camera showed Tang Yao, this young man who looked very embarrassed, his demeanor became extremely melancholy. A love song dedicated to the city. Millions of viewers in the live broadcast room silently listened to a song, and countless people burst into tears!
