The most speechless place for this building is that the arrangement is a bit disorderly. It is very slow to take the elevator upstairs. It seems that only one elevator is opened. It takes 10 minutes to transport a wave of guests to the second wave of transportation. It was even more exaggerated when I came down, with a maximum interval of 15 minutes, and a wave could only transport about 15 people. Later, there were too many people in line, and it seemed that other spare elevators were opened, coming down from the unconventional route.
