Diwang Mansion is called Diwang Mansion by the public because the highest price of land transaction in Shenzhen was obtained by auction of the land occupied in that year, which is inherent in the name of "Diwang". The building is 69 stories high, "King of the Earth sightseeing & window of Shenzhen Harbour" is located on the top floor of the King of the Earth Building, 50 seconds elevator can take you to it. On the surface, it seems that it's just sightseeing, but it's not. It's like an exhibition hall. It can learn a lot. I've been in Shenzhen for 10 years, and a lot of things just came up to it. So, if you want to know about Shenzhen, a city of speed, this is a very good learning platform. The lecturer will circle around the building, tell you the story of Shenzhen and know the geography of Shenzhen. Because of the high-level, we can see all over Shenzhen. There are also some old photographs of decades ago. Looking at this one, and comparing with the high-rise buildings in front of us, we really have a deeper understanding of Shenzhen's speed. After all, Shenzhen's speed of two and a half days and one floor is unique in the world.
