The current state of Cheongna Dome, which is dead serious about concerts.jpg

This was posted on the website of the company providing performance equipment for Cheongna Dome, and to summarize the main points:

1. There are 255 motor devices alone that can hang various stage lights and special equipment from the ceiling.
2. The mound can be hidden below the field using an ascending/descending lift (refer to the GIF).
3. Dedicated speaker passages were installed to capture the echoing sound characteristic of dome stadiums and to maintain overall sound balance.
4. Structures were installed to naturally conceal empty seats during small to medium-sized performances.
   When I saw the Shinsegae Group interview, they sounded like they were going to squeeze every bit of profit out of concerts, so I wondered how serious they were, but they are truly serious. wow;
