In this fall and winter alternate time, it is best to eat some nutritious food and to increase heat, and beef is one of the best options. There's a lot of beef that can be cooked, stewed, red roasted, etc., and my favorite and most common is ketchup, which sometimes eats at a Chinese fast-food restaurant outside, which, as long as it's available, is not as good as it is at home, it's cheap, it's clean, it's clean, it's more meaty
