Introduction to the Palace of Nations: The 41-meter-high hollow structure atrium is known as "a home square where kites can be flown". About 20,000 square meters of transparent and open space, surrounded by 300 shops, are dazzling. Ten thousand national flags are hung on the ceiling, indicating the international color of the Louvre. It can be called the United Nations of world furniture. Standing in the Hall of Nations, you can see half of the entire shopping mall's interior, which is majestic. The graceful figures of various skin colors and costumes coming and going are very shocking. Various furniture art activities are held here every year, becoming the epitome of Louvre art and culture.
