"Can one buy affordable fresh vegetables everyday at their doorstep?" Stockhausen asked the guide when entering the Shanggang Trade Market in Pudong New Area. 

Stockhausen was "astonished" after buying half a kilo of fresh tomatoes for just 3.5 yuan ($0.5) at a stall in the farmers' market.  

"I thought you would bargain. Now that you didn't, I will give you a discount of half yuan", said stand owner Ma, giving the change to Stockhausen.
