I was wandering around Xisi during the National Day. When I passed by the alley of Xisi North Street, I found a door with the words "Yidali" on it. There was a sign explaining it in the corner of the door. I looked carefully. Not small, now the relevant content on "Beijing Tourism Network" is transferred here and shared with DPER! Yidali Hutong: On the map of Beijing published in 1947, Wanrong’s grandfather’s Baylor Mansion, there is a place called “Yidali” near Beijing’s Xisi Fourth Street. A few days ago, I was walking near the east entrance of the courtyard alley on Xisi North Street. It was easy to find "Yidari". Yidali Hutong is a dead end. There is a brick doorway at the entrance of the alley, with the three characters "Yidali" written on the doorway. There are not many place names in Beijing, probably only Pinganli and Hepingli, and they only appeared in modern times. The same goes for Yidali. According to historical records, this place was once the residence of Prince Heshuoding. Later, when it was passed down to Beile Aixinjueluo Yulang, it was called "Langbeile Mansion". Yulang was a prominent figure in the late Qing Dynasty. He served as infantry commander and military minister. Yulang's daughter was named Hengxin. She married Rongyuan, and her daughter was Wanrong. Wanrong was the empress of Xuantong Emperor Puyi and the "last empress" of China. After the fall of the Qing Dynasty and the sixth year of the Republic of China (1917), Yulang took advantage of the situation and sold off the southern part of Baylor Mansion (today's Second Artillery Guesthouse area). The properties in the northern part were sold and turned into residential buildings, named "Yidali". Yidali only has a west entrance but no east entrance. Yulang's descendants gradually moved to other places. It is understood that one of his descendants of the Heng generation set up a book stall and sold popsicles on Longfu Temple Street before the "Cultural Revolution", and his life was not very good. Lambelle Mansion was originally the size of a prince's palace, covering a vast area, starting from Gangwa City in the west, to Prince Li's Mansion in the east, to Fanshang Hutong in the north, and to Yangpi City Hutong in the south. The place name "Yidali" is marked on the "1947 Map of the Western part of the Inner City of Peiping". The plaque in Yidali was written by the calligrapher Zhang Jixin, who was once Zhang Zuolin's staff and later the teacher of "Young Marshal" Zhang Xueliang. Zhang Jixin is a famous calligrapher. The plaques on the Fengtian Guild Hall and Northeast Yiyuan in Beijing were all written by him. After the "September 18th Incident", Zhang Jixin opened a Northeastern refugee camp in Deshengmen, Peking. When refugees asked for help, he gave them a piece of calligraphy to exchange for money. Zhang Jixin had contributed to the peaceful liberation of Peiping. After the founding of New China, he was employed as a librarian of the Central Museum of Literature and History. The plaque "Yidali" was written in 1936. It can be proved from this that Yidali only appeared after 1936, and the owner of its property was a big businessman in Tianjin. Nowadays, few people in Beijing know Tiyidali, but the Claypot Ju Restaurant outside the entrance of the alley is quite famous. It is said that this restaurant was first "affiliated" under the name of Prince Ding's Mansion and is famous for its white meat casserole. There is a common proverb in Beijing: "White meat in a casserole - don't wait until noon" refers to this.
