In the ideal city of Cerdà, all the controls are rational and beautiful, but with time passing by, urbanization and industrialization have increased the population. The neighborhood courtyard that originally belonged to each Manzana disappeared, buildings of various uses gradually fill up the center of manzana. The government has made efforts to restore part of the inner garden, but it is far from enough. People's outdoor activities are forced to gradually move away from their residences, onto the streets or further squares. The neighborhood space in Manzana is different from the larger social space. Similarly, the buildings inserted in each manzana are also different from ordinary buildings. The free social space that should be facing the neighbors has become a monotonous roof. Now, sharing these roofs can contribute to the social networking of the entire neighborhood.Follow Cerda's will to carry Utopia to the end.

Urban pharmaceutical industries are responsible for high intensity emissions of water pollutants. The regional water pollutant emission standards vary greatly throughout the Yangtze River Delta Urban Agglomeration (YRDUA) in China, which, to some extent, results in increased risks and hidden dangers to regional water environment safety, especially water quality. Under the national strategy of Yangtze River Delta ecological and green integration development, a unified standard of water pollutant emissions should be integrated into the integration development process, but differences between characteristic items, concentration limits, and conditions among four local standards of water pollutant emission have become a key influencing factor in their integration in industry and in green transformation. When comparing the water pollutant emission standards of the biopharmaceutical industry in three provinces and one municipality of the YRDUA, the factors influencing integration were determined and caused by the main differences in local water pollutant emission standards, namely, the race to the bottom of the biopharmaceutical industry, the inconsistency of environmental protection regulation law, and transboundary water pollution risks. From the perspective of urban water quality safety, we propose the following strategies for promoting the integration of water pollutant emission standards in the YRDUA: (1) increasing government funding for local water pollution governance and encouraging industries to adopt the third-party governance model for pollution control in the YRDUA; (2) unifying water pollutant emission standards and environmental law enforcement standards in the YRDUA with a mechanism involving shared economic responsibility; and (3) establishing a platform for sharing data and governance performance for the emission of water pollutants in the YRDUA.
