What do the above paragraphs mean? ['Institutional segregation makes it impossible for migrants to integrate into urban society.', 'The entry of floating population will lead to a dual structure within the city.', 'Let the floating population truly integrate into the city, the society can last long.', 'Solving the problem of separation of floating family members is the key to disrupting the dual structure of cities.']
