On the 163m glass platform, sightseeing is a kind of enjoyment. Although the glass is already dirty and out of shape, there are still many people who dare not go on it. But if you don't use the annual card, it's a bit expensive. The traffic is very convenient. The subway is direct. Generally speaking, it's very good. There's also a revolving cafe on it. It's beautiful, but it's a bit expensive. By the way, without time limit, you can stay on it for two small ones. When the weather is good, you can stand on the platform for a while and enjoy the fresh air.
