A way to prepare them:
1 Clean the mushrooms and soak them in water. Wash and peel sweet potatoes and then cut them into cubes.
2 Put sweet potatoes into boiling water until cooked.
3 Fry mushrooms and add water to further soften the mushrooms as well as soy sauce and sugar.
4 Stew them until the water boils. Turn down the heat and cook for another 10 more minutes.
5 Add sweet potatoes in the soup and add salt and starch for seasoning.
3 For those who have cold hands and feet all the time, this method works well. Bathe cold feet and hands in cold water for a while and then dry them. Wear socks and gloves, and the hands and the feet will warm up soon.
