A well-known artist Liu held his solo concert in Shanghai twice in 2009. Among them, the first box office revenue was very good, and all the tickets were sold out one month before the performance. Therefore, the artist's brokerage company decided to hold Liu's solo concert in Shanghai again one month later, which was the same scale as the first time. However, the second box office revenue was not ideal, and only 40% of the tickets were sold.
The most likely reason for the decline in box office revenue of the second concert is that the program arrangement of the second concert is the same as that of the first concert, and many people have participated in the first concert, so they will not participate in the second concert.
