It's still good, how to say. When we go there, there are a lot of people, but not the most time, the tour guide, the most time, people are crowded, and the queue is about an hour, so we stand in line for about 20 minutes. So we go in and say it's really frightening. Very high, but there's also the kind of place on the side that dare not walk on the glass floor. It's iron plate, not it. Transparent, bold enough to walk in the middle. It's not so terrible. You have to wear shoes with it for free... Heart disease, high blood pressure, don't go.
