Ganxi House is located in Qinhuai District, Nanjing, built in the Jiaqing period of the Qing Dynasty, and built by the Qing Dynasty literati and Fang Zhijian Fang Xi father and son for several generations. It is commonly called "99 and a half rooms", but there are actually more than 300 rooms, with Ming Xiaoling and Ming City Walls and the three major landscapes of Nanjing, which is the largest and most complete ancient famous buildings in Nanjing, and is also a key cultural relics protection unit in the country. The former residence of Ganxi consists of three groups of five-entry-style ancient buildings, which belongs to the typical four-water-style system in the south. The vertical spatial layout of the north and south is rigorous, and the horizontal space of the east and west is relatively soothing, making the architectural community in the house garden rich and varied. The three axes of left, center and right are used in the plane layout as a group of symmetrical forms, which can be seen from this, the main and the low, the high and the low, the low. In terms of layout, the characteristics of the palace building "front hall and back bedroom", "center and center", "inside and outside", and the hall, the car hall, the hall, the back hall and the back hall are divided from the north to the south. Each hall has different functions of use; on the architectural decoration, each group of buildings is separated by the horse head wall. The large courtyard is decorated with mountains and stones and trees. Most houses are grid doors and closed windows. The skirt board is decorated with auspicious patterns. Its architectural characteristics are blended from north to south, with both the "green brick small tile horse head wall, the corridor hanging flower grid windows" and the beautiful and elegant Jiangnan houses. There is also the thick atmosphere of the northern "horse race building". The actual number of tourists going inside on weekends is not much. Most of them still take ancient wedding photos or art photos. Parking around is also difficult to find a location. One of the advantages is that the tickets are very cheap.
