Years ago I visited this place and left screaming as I ran down the hall. I was in such a fright I decided to take the stairs-and there was a great handwritten sign on the door. I took a picture of it and posted it on another site...it said, in Chinese and English “No running, no yelling!”. Of course I didn’t pay heed, and continued running down the stairs screaming like a wild Banshee until I got to Mott St and was able to disappear in the crowd!
