Delightful scenes like this occur everywhere on the streets of Shanghai. There are many vendors selling a variety of foods, fruits, and vegetables and, of course, flowers. It is hard to tell the difference between vendors that are legal and have permits and those which are illegal and don’t have the requisite permissions. One way that you know is that with the appearance of a cop, the illegal vendors pack up quickly and move on. But most are back as soon as the authorities have disappeared.
