In his senior year of high school, Lin Nanzhi wrote a book called "South Wind Handbook" to record the youth of his classmates. When the manual was circulated and torn into pieces, Zhou Jibai clearly saw it, but chose to remain silent. Seven years later, when the old school was demolished, she returned to Nancheng No. 7 Middle School for an archive exhibition and dug out a suppressed request for help record at the old radio station. Everyone advised her to write down past events as youthful pain, but she checked files, interviewed people involved, and re-established a response mechanism. Zhou Jibai wanted to use a late reply to explain that year, but she only asked: Why didn't anyone respond at that time? The old school will be demolished and the youth will be turned over, but the ignored voice cannot be pushed back again.
