(Of course, Wuqing County has now become a district of Tianjin. There are many delicious foods in Tianjin, except for the "Three Musts" (Tianjin "Goubuli Steamed Bun", "Guifaxiang" 18th Street Twist and Erduoyan Fried Cake), which are fried by its impressive Erduoyan. That small shop is close to where I live. When I was a child, I walked less than one meter through Erduoyan. At that time, the "ear-eye" fried cake was made of peanut oil and sesame oil. Crispy outside and tender inside, sweet and delicious. Unfortunately, it's too expensive (one eighth) to eat. But that smell is really hard to forget. In this sense, good things (no matter what) have a long history and are endless. I don't think expensive things are necessarily good things. Only what has really been handed down is "expensive". What matters is its "truth"!
