Yanle Hutong is located in the southeastern part of Dongcheng District, Beijing. Its name originates from the Yanle Bureau, an institution under the Jiaofangsi (Imperial Music Office) during the Ming Dynasty, which was responsible for rehearsing and performing ceremonial music.
At that time, the Jiaofangsi had a clear functional layout within the neighborhood: Yanle Hutong was designated for performances, working alongside Bensi Hutong (administration) and Goulan Hutong (now Inner Affairs Street, used for rehearsals), forming an integrated system for court music and entertainment.
Within No. 92 courtyard of Yanle Hutong stands an ancient jujube tree with a trunk diameter of 1.1 meters. Estimated to be 500–700 years old, it is an important protected ancient tree and a notable natural landmark of the hutong.
Dongtangzi Hutong is an ancient alley located in Beijing's Dongcheng District, with a history of nearly 800 years. Stretching over 700 meters, it connects to Xiehe Hutong on its southern side. It is one of the oldest hutongs in the city and was once among the best-preserved.
During the Ming Dynasty, it was known as 'Tangzi Hutong' (in old Suzhou–Shanghai dialect, 'tangzi' referred to brothels). In the Qing Dynasty, to avoid confusion with another 'Tangzi Hutong' located north of Jinyu Hutong, this hutong was renamed 'Dongtangzi Hutong' (East Tangzi Hutong), while the other became 'Xitangzi Hutong' (West Tangzi Hutong). During the Cultural Revolution, it was temporarily renamed 'Ruijin Road 12th Alley', before later reverting to its original name.
According to Qing imperial archives, the Qing court regarded the Zongli Yamen as a crucial institution for state affairs. When planning its establishment, the court initially considered locating it within the imperial palace. However, due to the frequent diplomatic interactions that would require foreigners to enter the palace—something deemed inappropriate—the final decision was to situate it in Dongtangzi Hutong, not far from the Forbidden City. Officials from the Grand Council were assigned to work there concurrently, traveling regularly between the palace and Dongtangzi Hutong to deliver confidential documents.
Dongtangzi Hutong is closely connected with modern Chinese history. It was not only the site of the Qing dynasty's foreign affairs office, the Zongli Yamen, but also home to many influential figures in modern China, including Cai Yuanpei, Shen Congwen, Wu Jieping, Lin Qiaozhi, and Ding Xilin, all of whom made significant contributions to China's cultural, scientific, and intellectual development.
东堂子胡同是位于北京市东城区一条有着近800年历史的古老胡同，长700多米，胡同南侧与协和胡同相通。是北京城中历史最悠久的胡同之一，也曾经是保存最完好的胡同之一。
明代，称“堂子胡同”（旧时苏沪方言称妓院为“堂子”）；清代因与“金鱼胡同”北面的“堂子胡同”重名，遂将此“堂子胡同”改称“东堂子胡同”，彼“堂子胡同”改称“西堂子胡同”；“文化大革命”中一度改称“瑞金路十二条”，后复称“东堂子胡同”。
据清宫档案记载，清廷视总理衙门为军国要地。为了保证国家机密不被泄露，筹建总理衙门时，曾一度在紫禁城内选址。由于考虑到署内的外事往来频繁，让外国人出入于宫禁之地，显然不合体统，后决定选址在离皇宫不远的东堂子胡同，由皇帝身边派出军机章京到总理衙门兼职，往返于宫内军机处与城东东堂子之间，定期将机密文件转送宫中。
东堂子胡同与中国近代史有着密切的联系，在这条胡同中不仅坐落者清朝末叶专司外交事务的总理各国事务衙门，还有蔡元培、沈从文、吴阶平、林巧稚、丁西林等对中国近现代历史文化科技发展有着举足轻重影响的历史文化名人的故居。
