The photo is taken near the Renmin Bridge in the old city of Guangzhou where we find wholesalers markets. The goods meet here, then they will be transported by trucks to the other cities. The landscape contrasts with the image of the historic citis.In people's impression, the historic cities must be elegant with a traditional architectural style and carefully decorated shops.Indeed.But it is not the case represented in the photo. In fact,the market appeared several centuries ago when the city was very small. Today, the market is located in the center of the city, which has already been enlarged several times. Even if it no longer corresponds to the modern urban image, it resists. This persistence proves that the functioning of stock and flows constitutes the essential characteristic of cities.
