"What happened next?"
No one answered.
In 2013, a girl on the Loess Plateau wrote these three words at the end of an article, and then stopped writing.
South of Qinchuan, another girl by the Anjiang River read the blank. That night, she used the guitar for the first time and wrote "What happens next" into a melody.
They still don't know that the unfinished ending is waiting for an answer.
Concept: A question is written down, a melody is played, and a mountain and ten years are separated in between. What this book wants to express is: Every sound a person makes in this life will never really disappear - it is just waiting for another frequency to catch it.
