I once had a dace and mustard soup at Tiantian fishing port in Pudong, Shanghai. It costs 28 yuan for a small bowl. My heart aches. My big bowl is only four yuan. I asked the Cantonese speaking foreman why it was so expensive. How much did it cost? The handsome man said with a smile, no way. Both dace and mustard come from Guangdong by plane. Don't compare the price of Guangdong with it. Then you can eat more comfortably.
