As the saying goes, "You are what you eat". And according to a manufacturer of mung bean cakes in Shanghai, if one eats its product labeled "dog poop cake", you are likely to be "blessed with the kind of luck that would see you step on dog poop".

While tourists in the city have been intrigued by the product, locals are said to be indignant that the manufacturer is calling it "a specialty of Shanghai", leading to production of the cake being suspended and the product being pulled from shelves since Wednesday, after receiving wide media attention.

"I don't get it. I just want to be innovative, which is supposed to be encouraged," said Zhang Neirong, owner and manager of Shanghai Fengdu Food Co, which began labeling its signature mung bean cakes as "dog poop cake" this year.
