Inside-out Hardware store on Beijing Lu

Shanghai's Beijing Street is an odd place - you can buy any sort of hardware you might need, from electronics to 6 inch water valves and everything between. They are all sold in little shops or stalls, but it's like a Home Depot exploded, spawning hundreds of little specialized vendors for blocks and blocks. And they are often very busy, with guys on scooters running in and out with hoses, lights, and everything needed to support one of the world's fastest growing cities.
