The furnace bag is fried face down, and most of the fried bags are fried face up. The fillings are also slightly different. High-density furnace bag is mainly leek meat, Chinese cabbage meat, shrimp dishes and so on. Moreover, there are more kinds of fillings in fried buns, and the size of furnace buns is larger than that of fried buns.

Gaomi people call fried buns "packages". Why is it called a packer? I think it has something to do with the expression customs of Gaomi people. Gaomi people often say that they beat wheat, fish and dates. When I was a child, I used a briquette stove to make a fire at home and fried it with aluminum pot. When cooking, I heard the sizzling sound of wok in my ears, and smelled the smell of vegetable meat and oil in my nose, which was very attractive.
