First, strengthen physical exercise, especially those who sit for a long time or stand for a long time. They must pay attention to intermittent exercise, do more hands and feet and waist activities, and strengthen blood circulation. Second, pay attention to diet, eat more warm food, and improve the body's cold tolerance. Common warm foods are: cow, sheep, dog, chicken, garlic, pepper, ginger, onion, yam, longan and so on. Three recipes 1. Sliced mutton with shredded ginger. Shred ginger. Add a little oil to the pot and bring it to a high fire. When the oil smokes, add pepper and star anise, stir-fry until fragrant, add shredded ginger, stir-fry, add mutton slices, add salt and monosodium glutamate, and pour sesame oil out of the pot. 2. Red dates, mutton soup and mutton soup are cut into eight pieces, and the bleeding water is soaked in the water pot for later use. Wash jujube and wolfberry for later use. Add water to the pot, add mutton, onion, ginger and aniseed and cook together. When it is half cooked, add jujube, medlar and salt, and then cook. If you don't like the taste of mutton, you can add one or two pieces of orange peel to increase dates to reduce the smell. 3. Three kinds of peppers (choose pepper varieties according to their own hotness), put them on the fire and dry them until they are close to burnt; Peanuts, fried until crisp (sesame seeds are also acceptable); Bake the scallion on the fire until the outer layer is burnt, and peel off the outer layer. Mash the above three raw materials in a mortar, then mix them together and add salt and monosodium glutamate. For friends who like spicy and coarse grains, this dish is the most delicious-the participation of three spices in pancakes and stuttering is the most enjoyable. When eating "Golden Pagoda" (Wotou), it is also a pleasure to put three spices in the hole of Wotou!
