Among the visitors at the TR Mall, there was a large proportion of young people, with many parents bringing their children to visit. They hoped to expose their children to science and technology early and cultivate their interest in it.

However, Tan Rou also saw some elderly figures among the crowd, holding cameras and taking pictures. While taking pictures, they exclaimed in admiration, saying that such an event was really great.

The visiting hours were from 9 a.m. to 5 p.m., and visitors needed to prepare food and water in advance because once they went out to buy something, they could not come back in again—the QR code could only be scanned once.

Originally, the QR code could be scanned twice, but with a sudden increase of nine thousand people, it had already added a burden on the TR Mall, so Tan Rou changed the visiting system a bit. She shortened the time and reduced the number of visits.
