The overall feeling is OK, the ticket is very convenient, the surrounding landscape is better, and the traffic is convenient. Because I arrived before the peak period, the queue time to go up was not long, about ten minutes, but when I finished the tour, I queued for about 20 minutes. There are more people in the venue, and it is more difficult to take a single photo. There will always be people who accidentally enter the mirror. But after all, it is an iconic building, and it is worth visiting once.
