this friend: Bayi road at the south gate of Chongming is the most prosperous in Chongming. Bayi road is both a pedestrian street and a commercial street, and it is also a civilized street named at the municipal level, just like Nanjing road in Shanghai. The so-called prosperity, as far as I am concerned, should meet the following conditions: first, commercial and trade gathering areas; Second, the local government focuses on supporting areas of concern; The third is the most popular area and so on.
