It turns out these spanich was nutured by California Cattle Feces. So for you and your family's health, better ask what feed was used when the vegetable is cultivating before you make a purchase.
Alex,it seems something wrong in your discription. After I look up the blog of "my father's hand", I found the father of the blogger is called Samuel Wray.
Alex, I am sorry! It seemed that I didn't carefully read your post when writing my earlier comments. Now I see, the jeans ball was actually exhibited in a exhibition center in Xiamen instead of in a shopping center there.
The photo above was an art installation seen in Shanghai as early as in May. The idea of the similar jeans stack in a Xiamen shopping center is thus possibly coming out of there.
Good blogging, Miss c!
