I listened to the song "Wait Until You Are Thirty-Five" not long ago. At first I thought the lyrics and music were very artistic and I liked it very much. Later, I casually went to Baidu and realized that there is actually such a sad but beautiful story behind this song. I read the story of Nankang again in the morning. I couldn't help but appreciate it, feel sad, and feel distressed. I always felt that I had to do something to calm down my turbulent mood.
