The city centre is clean because you can see a lot of cleaners around, they are equipped with tongs for picking up rubbish especially small ones.
But at the outskirt of the city is not so clean. There are many trishaws at night at the city outskirt. Wenzhou is perhaps famous for its machinery and shoes making factories.
Bad, the street is badly develop. No way compare to ningbo. It pop up building as they wish, that why shopping is also messy.
