One thing that I have observed in Shanghai is that they love dogs! I always see people walking their dogs in the evening, and 90% are toy dogs. Although they walk there dogs, I never really see dogs pupu in the road side. Hmmmm...this is because they clean up their dogs pupu! They don't just leave their dog shit around the place and let it turn into fertilizer on the road. Somemore people tell me that Shanghai people will take their pants off and pupu whenever they feel like it. They will pick it up using plastic bags and throw it in the bin. I have seen it with my own eyes.
I am ashame, because I am one of them that leaves the pupu to dry on the road. Are you?
