在绿树掩映之下,成片的灰墙和规整的四合院落宁静而和谐,景山、北海、天坛、故宫中的古建筑突兀其上。天、地、人浑然一体,这是老北京的建筑特色。将来也许有一天,鳞次栉比的高楼越来越多了,成片的四合院几乎没有了,北京只剩下几个孤零零的 Under the shade of green trees, a series of gray walls and regular courtyard courtyards are peaceful and harmonious, and the ancient buildings in Jingshan, Beihai, Tiantan, and the Forbidden City suddenly rise above them. Heaven, earth, and people are all in one, this is the architectural feature of old Beijing. Perhaps one day in the future, there will be more and more high-rise buildings lined up, and there will be almost no more courtyard houses. Beijing will have only solitary ones left.
