Fushun Zhai's braised beef, Ruibing Lou's stuffed flatbreads, Kangjia's old tofu, along with Nian Gao Qian, Bao Du Feng, and Baozi Yang, all contributed to making the Dajialang area the most vibrant part of Beijing.,Chen Qi walked a few steps and arrived at the entrance of Building 12. A sign on the door read: Xinhua Bookstore Dormitory.,It used to be where Zhang Henshui lived. There were seven courtyards before and after, which was unusually spacious. Zhang Henshui lived here for 3 years and wrote "The Golden Powder Family". Later, he went to Nanjing, and the courtyard changed hands several times and became a dormitory.。
