The Former Site of the Eighth Route Army Xi'an Office is located at Qixianzhuang, Beixin Street of Xi'an City in Shaanxi Province. After the peaceful settlement of the Xi'an Incident, the CPC established a Red Army Liaison Department here. In September 1937, it was turned into the Eighth Route Army's Office. The main work of the office was to enfold the united front work, to send progressive youth to Yan'an and to ship war materials to the Shaanxi-Gansu-Ningxia Border Region and the front. Zhou Enlai, Zhu De, Liu Shaoqi, Peng Dehuai, Ye Jianying, and Deng Xiaoping came to the office several times to guide work. Due to the all-round Civil War launched by Chiang Kai-shek in June 1946, the office was withdrawn back to Yan'an in September. In 1988, the State Council of the PRC declared it one of the major historical sites under the State protection.

The Former Site of the Eighth Route Army Xi'an Office, built in 1936, is composed of Court 1, Court3, Court 4 and Court 7 at Qixianzhuang. Court 1, consisting of the north court and south court with the similar size and structure, is the main place for handling official business. It occupies a space of 1,300 square meters, 82 meters long from south to north and 17 meters long from east to west. The houses are of single-storey brick-and-wood structure with unfired bricks for the inside wall and fired bricks for the outside wall. Doors are available in three directions, south, west and north. The main buildings of these two courts are somewhat H-shaped, five-bay wide from the east to the west and six-bay deep from the south to the north. The ground is 80 cm above the earth's surface with an underground room available. Court 3, Court 4 and Court 7, separated by Court 2, Court 5 and Court 6, are arranged to run toward the east one by one but their structures are more or less the same as Court 1. Court 2 and Court 4 were used by the various departments affiliated with the office and used as functionaries' residences while Court 7 was a hostel.

After the completion of renovation in 1959, Court 1 was turned into the Memorial Museum of the Eighth Route Army Xi'an Office. The museum has a collection of 907 items of historical relics, 3,327 photos and 500 articles of reminiscences. The historical relics include the things left behind by Zhou Enlai, letters written by Zhu De and Lin Boqu, the instruction telegrams sent by the Central Committee to the Eighth Route Army's Xi'an Office and the daily working records of the office. The museum once held a photo show of Zhou Enlai, Liu Shaoqi and Zhu De. In 1984, the main buildings of Court 1 was renovated on a large scale and reinforced while part of the buildings in Court 3 and Court 4 were maintained and repaired.
