In Ming Chenghua period, after the diversion of the Han River, Hankou thus appeared. Due to its excellent waterway environment, merchants gathered in Hankou and Hankou's business was booming. Because of the isolated island pattern, Hankou's government was loose in the beginning, and spontaneously formed associations and gangs to manage the local place, where balanced governance structure just like the crystals took shape and achieved local autonomy. Due to the lack of offi cial intervention, Hankou took the fi shbone-like spatial form with rich and diverse daily life and less social exclusion, constituting a harmonious business social community. The port of Hankou opening in 1861, giving rise to changes in the economic structure, local self-government began to collapse, which was replaced by offi cial exhaustive monitoring. After the collapse of the autonomy, community began to differentiate. In the process of city center transferring to the concession, spatial differentiation took shape in Hankou. Due to the impact of the new economic logic, Hankou wall was built into the street, and "street economy" started to come out and changed the "waterway economy". At the same time, the scale of cities was also enlarged, and the unifi ed construction model of straight roads and the new residential became popular. As a result of the police system, social ecology was greatly bruised, and local autonomy was totally replaced by the offi cial governance.
