Fourteen years ago, I went to Madison Square in New York to listen to Madison Square's concert. It was their first concert in New York. There were many Chinese people attending the concert that day, both old and young. However, the most expensive seats in the front row were not sold out. Although we bought the cheapest mountain top tickets, we were persuaded by the security to take the most expensive tickets. Only later, I found that it was not good to sit under the stage, because the fans were really all shouting and jumping, which made me unable to sit down and listen to the song, because once you sit down, you can only see you. The front man's ass.
