"Three lanes and seven lanes" is located in the center of Fuzhou, which is the general name of ten lanes arranged from north to south on both sides of Nanhou Street. The "three squares" are: Yijinfang, Wenrufang and Guanglufang; The "seven lanes" are: Yangqiao Lane, Langguan Lane, Taxiang, Huang Xiang, Anmin Lane, Gongxiang and Jipi Lane; Since the Han Dynasty, Fuzhou has built six city walls, including Yecheng and Zicheng. The city expanded from north to south. The overall layout takes Pingshan as the barrier, Yushan and Wushan as the confrontation, South Street (Bayi Road) as the central axis, with lanes on both sides, paying attention to symmetry, and gradually forming a street with three lanes, seven lanes and one street ("street" guide).
The panorama of three lanes and seven lanes was formed in Wang Luocheng in Tang Dynasty, with antai river as the boundary in the south, political center and aristocratic residential area in the north and civilian residential area and commercial area in the south. At the same time, the symmetry of the central axis is emphasized, and walls are divided on both sides of the southern central axis. These residents became the beginning of the alley, forming today's three lanes and seven lanes. This is the origin of the three lanes and seven lanes.
