That's too much. According to my own experience, I will make a brief introduction by region: the number of duck tongue biscuits is "Nanyan Village" (it is recommended to eat with Tang Yang in Yancun Village); The smell of Daming stone cake attracted immortals to jump over the wall. Of course, the stone cake belongs to Daming (although it is not eternal, this information right should be given away); Further north is the "famous pass". As the most developing town, the bean jelly there is unparalleled, and it is known as "Xiaotian cuisine", ranking first in the world; Then, the pace goes east and reaches the third town of Yongnian, "Dabeiwang". Pancake fruit is very famous in the local area and has the reputation of "Little Tianjin". This is the most representative pasta in Yongnian three towns. Of course, the rest of Yongnian depends on your field experience!
