Introduction from the Ministry of Foreign Affairs: The office building of the Ministry of Foreign Affairs is called "Itamaraty Palace". The building is surrounded by a pool and is blocked by glass. White clouds, blue sky, water and high-rise buildings form a beautiful and extraordinary picture, which is known as for Crystal Palace. Looking from a distance, there is a round boulder floating on the lake at the main entrance of the Crystal Palace. When you walk in, you see that it is actually five strange-shaped stones twisted together. This ball symbolizes the whole world, and the five strange rocks represent the five continents of the world.
