Crazy House, the "world's most amazing building". Designing Crazy House is the daughter of the former president of Vietnam. Presumably this Vietnamese princess must be a fan of fairy tales, and each of her designed cottages has a strong fairy tale. Feel free to choose an entrance to enter the building, along the exaggerated and strange stairs, go up and down, and sometimes walk on the roof, sometimes through the grotesque bridge in the sky, sometimes encounter the solidified "magma", sometimes hit the rope The huge artificial "cobweb" was sometimes scared by a "giraffe" emerging from the bush.
