The word "triptych" always makes people have a little respect, whether it is a publishing house or a bookstore, triptych is a benchmark in the industry. Beijing Sanlian Taofen Bookstore is a large-scale cultural enterprise founded in 1996 by Life, Reading, and Xinzhi Sanlian Bookstore. The bookstore has been losing money for more than ten years since its opening, and in 2010, it was restructured into an exclusively controlled company limited by shares and renamed Beijing Sanlian Taofen Bookstore Co., Ltd. After the restructuring, the bookstore carried out modern enterprise management, and turned losses into profits at the end of 2011, which is of exemplary significance. Now Sanlian is a famous cultural landmark in Beijing, with nearly 90,000 kinds of books. At the beginning of 2014, Joint Publishing decided to establish a 24-hour bookstore on the basis of the original Beijing Sanlian Taofen Bookstore, renovating and adjusting the layout to show a new look. Sanlian Taofen mainly deals in philosophy and social sciences, literature and art books, as well as the sales of audio-visual products and cultural and creative products, and regularly and selectively organizes more than 100 marketing activities such as lectures, new book releases, seminars, exhibitions and other marketing activities of publishing houses including Sanlian Bookstore every year. The overall environment of Sanlian still has the feeling of a state-owned enterprise, the main books are concentrated on the basement floor, the first floor is mainly new books, recommendation counters and audio-visual products, and the second floor is the Sculpture Time Cafe. In addition to books, the store also sells traditional goods such as calligraphy and stationery, but the quantity is not large, and there is no strong commercial atmosphere. In the depths of the night, there were many readers sitting on the three-story staircase in front of the podium, and reading was very atmospheric. The light is not dazzling, it is comfortable, and it is suitable for reading. However, the Joint Bookstore is now undergoing an upgrade, and the night market service is now suspended.
