The beginning and end of the dismantling of Beijing's ancient city What are the revelations and lessons for the development of the city now?

(1) The ancient city of Beijing, as the most important overall material culture of Beijing's traditional culture, has not been preserved. As Mr. Wang said, "Such a city is not only not found in the ancient times in the whole world, but also in the modern times, with the most progressive theory of urban planning, it still maintains the most favorable conditions." "We should take care of the cultural relics and buildings, not only for the individual hall, hall or tower, but also for the whole surrounding and neighboring environment. We cannot sit back and watch, nor can we tolerate a magnificent building or a group of buildings being subjected to all kinds of direct or indirect damage, so that they are entrusted to an irreconcilable surrounding and subjected to undue slaughter."
