This is not a square, is a part of the road. I call this place "La piazzetta" because from 9p.m to 3a.m. it seem like a little square. People from the alleys came there whit stalls selling Miàn (pasta), Ròu (different meat), etc ... In some period of the year they are not allowed to come there, because after they moved out the road is totally full of waste. They can be charged from 500RMB to 1000RMB. But police keep an eye closed, they know these families need to work and people love to eat open air; so there are some period of the year, like summer, with big activity and other without "La piazzetta". In this case families work in the alley, of course with less costumers.
