The invention of electric lights in the 19th century brought great convenience to people's production and life, and this lighting technology was quickly introduced to China. In the fourteenth year of the Guangxu reign (1888), Empress Dowager Cixi prepared to return to power over Emperor Guangxu and retired to Xiyuan (now near Beihai Park in Beijing) to rest for the rest of her life. In the first half of that year, the Qing government purchased steam direct current generators and lighting materials from the Qiluofu Trading Company and installed them in the helmet shaped alley outside the west wall of the Yiluan Hall. In November, the above equipment was installed and supplied power to Xiyuan. At the same time, Xiyuan Electric Light Office was established. On December 29th, Emperor Guangxu's teacher Weng Tonghe wrote in his diary: "Electric lamps shine in the Forbidden Forest." As can be seen from the above, the earliest electric lamps installed in the Qing Dynasty palace were in the West Garden. In the 17th year of the Guangxu reign (1891), the Qing government installed a generator set on the south side of the Yelu Chucai Temple (now near the Wenchang Pavilion of the Summer Palace) to supply power to the Summer Palace, and established the Summer Palace Electric Light Office to manage the electric light affairs in the park. Due to opposition from conservative forces within the Qing court, the installation of electric lights in the Forbidden City was later compared to the Western Garden and the Summer Palace. In the 33rd year of the Guangxu reign (1907), electric lights began to be installed in the Forbidden City. At this time, Cixi had been using electric lights in the Summer Palace and West Garden for many years, fully feeling the convenience it brought. Dancer Yu Deling from the late Qing Dynasty entered the palace in the 29th year of the Guangxu reign (1903) and served as the imperial translator for Cixi for two years. She recalled in "The Unofficial History of Cixi" that "Cixi had little fondness for other new ideas or tools, but was particularly pleased with electric lights..." In addition, according to the "Beijing Electric Power Industry Chronicle", on August 17, 1904, the Qing government approved the establishment of the Jingshi Huashang Electric Light Co., Ltd., which was responsible for supplying power to the capital. At this time, Cixi, who lived in Ningshou Palace, intended to use electric lights in his residence. On November 26th, the 33rd year of the Guangxu reign, the Fengchen Yuan of the Ministry of Internal Affairs purchased 25 imperial houses in the Dabei Yuan for the installation of power generation machines, and established the Ningshou Palace Electric Light Office, which was under the management of the Xiyuan Electric Light Office. The Da Bei Yuan Chao Fang is located at the northwest corner of Beichizi Street, about 500 meters from Donghua Gate. In the 34th year of the Guangxu reign (1908), both Empress Dowager Cixi and Emperor Guangxu passed away, but the expansion of the palace's electric light circuit did not stop as a result. In the first year of Xuantong (1909), Empress Dowager Longyu issued a decree requiring the installation of electric lights inside and outside the Jianfu Palace, Changchun Palace, and Imperial Garden, and the installation of electric lights began with the main hall of Jianfu Palace. Among them, Jianfu Palace and Changchun Palace are located in the western area of the inner court, while the Imperial Garden is located in the central axis area of the inner court. At the end of the third year of the Xuantong reign (1911), the electric lights in the buildings in the inner court area of the Forbidden City were basically installed, and the power supply method was also modified to be supplied by Jingshi Huashang Electric Light Co., Ltd. Among the old photos in the collection of the Forbidden City, there are photos of the interior of the Qianqing Palace from the early 20th century. In the photo, above the throne and in front of the grand plaque, there is a chandelier hanging. This chandelier consists of a lamp holder, lampshade, wires, and bulbs. The lamp holder includes 7 small aperture bracket tubes, 6 hollow arc shaped decorative panels, and 1 lampshade at the bottom center. Each bracket tube contains electrical wires. The lampshade contains a light bulb, and at the ends of each bracket tube, a light bulb is pulled downwards, resembling an imperial crown
