Relics Gallery Introduction: The "Relics Gallery" is a section of the ancient city wall of the Ming Dynasty protected by the famous writer Zhang Xianliang using the most advanced "reversible" protection measures in the world. Walking inside, people can see the remains of the ancient city wall of the Ming Dynasty through the glass under their feet. The Western Cinema on both sides of the wall uses blue and white techniques to reproduce the life, production, and entertainment methods of the ancients.
