China people's preference for food has greatly promoted the development of the whole food culture. Nowadays, China cuisine is not only the most basic function of bringing people enough food and clothing. On the historical stage, China cuisine has become a cultural symbol, such as "Three hundred lychees a day, and I don't hesitate to grow up as a Lingnan person", "The autumn wind starts, the crab's feet itch, and the navel is round in September and pointed in October", and "It's no use eating all over Shanxi" and other folk sayings are expressed respectively.

In Shenyang, a special snack named tou is well-known at home and abroad. It is a kind of food made by kneading dough with flour, flattening, rolling, thinning and filling the dough by hand, folding it into a rectangle, and then wrapping both ends tightly and frying it. It is golden in color, tender in skin and tender in filling, and delicious in taste. It is one of the famous local snacks in Shenyang and one of the eight local snacks in Shenyang. "Hui tou" is similar to pot stickers, but it is slightly larger than pot stickers, with more stuffing, rectangular shape, no sealing at both ends, and it should be folded back to the middle, folded and fried. Add vinegar and garlic when eating, and the taste is excellent.

Huitou has a long history. According to legend, during the Guangxu period of the Qing Dynasty, a family named Jin opened a biscuit shop in the north gate of Shenyang to make a living. Business has been bad because of poor management. One day was the Mid-Autumn Festival, and the business was even more depressed. At noon, no diners came to the door, and the shopkeeper was at a loss. So he took out a few copper coins from the iron box, bought some beef and chopped it into meat at home, rolled it into thin skin, and wrapped it up in folds for his own holiday. At this time, a messenger suddenly came in from the outside, and when he entered the store, he saw that the food branded in the pot was novel in shape. Once tasted, it tasted very good. The messenger immediately told the shopkeeper to bake another box and send it to the inn. After eating, everyone exclaimed in unison. Since then, this kind of food became famous for a while, and the government and the people rushed to buy it, and the business was booming, so it was named "Back". There is also a saying that the name is based on the practice: because you have to turn around when you pack, it is called "turn around".

The husk is made of flour, which belongs to the staple food. It contains sugar, vitamins, etc., and is the main source of human heat. The back stuffing is vegetables and meat, which is very reasonable. Meat is rich in high-quality protein, while vegetables contain vitamins, cellulose and trace elements. Studies have shown that it takes 4-5 hours for meat to be digested in the gastrointestinal tract, and if only meat is eaten without vegetables, its nutrient absorption rate is 7%; Adding vegetables not only tastes good, but also improves the nutrient absorption rate to about 8%. In addition, meat belongs to acidic food, while vegetables belong to alkaline food, and the collocation of meat and vegetables is more conducive to acid-base balance. Eating back is good for controlling the amount of food you eat, which is difficult for many other foods to achieve. In order to eat scientifically, nutritionists advocate "seven or eight points full", which is difficult to measure accurately when eating rice and noodles, but can be counted after eating, especially for diabetics, obese people and people who limit their food intake. Therefore, "life needs to turn around more" is not only people's love for expressing delicious food, but also the exploration and summary of scientific diet by ancient Chinese.
