Tangerines, also known as oranges, are the fruit of certain plants in the citrus subfamily of the Brassicaceae family. Often referred to collectively with mandarin oranges, tangerines are brightly colored, sweet and sour, and are one of the most common fruits in daily life, and their peels can be used in medicine. There are many types of oranges, with slightly different shapes, colors, and listing dates, but picked, the method is similar.
