I can't figure it out. Why do I have to pay the ticket for the 6th IDC Annual Industry Festival this year?

Hello, I'm from IDC Circle Ceremony Organizing Committee. We have considered many factors in charging this year. On the one hand, we can control the participants, on the other hand, the scale and level of the conference have improved compared with previous ones. Held in Beijing National Convention Center, with a conference scale of 2000 people. There are many innovations in the theme and content of the conference, and many experts and scholars will make in-depth analysis in the fields of technology and market. In addition, the tickets for the conference also contain rich contents. There will be a very high-end cloud computing information encyclopedia, with external value of 800 yuan, 20 12 IDC industry information encyclopedia, which will be given away for free after ticket purchase.
