The tall building we are now passing is the gate of military prowess, the back door of the Palace Museum. Our visit is now drawing to a conclusion but the architectures of the Palace are not . On the other side of the road is the 43-meter-hign Charcoal Hill , providing natural protection for the Forbidden City. This was also an embodiment of China` s construction style-putting a pool in the front and a hill in the rear. Now let` s climb up to Wanchun (Everlasting Springs ) Pavillion where we` ll have a great view of the Palace Museum.
