If it is that kind of olive, or jujube-sized, oval and golden-skinned, it is called kumquat, which can be eaten when it is ripe! But unlike ordinary oranges, its skin can also be eaten, and the skin is the best.

There are two varieties of Xiaojin orange. A kind of fruit is very standard oval, and the skin and meat are delicious. One is a rare oval shape, but the fruit is a little sharp. We call it goat milk kumquat there. Its skin is sweet and fragrant, but its meat is very sour. Except those who love sour food, most people feel sour and bitter when licking it.

If that kind of orange is flat and round, the size of a child's fist and the peel is orange, it is a potted orange, which is mainly used for viewing, especially during the New Year, but its fruit is completely for viewing, sour and bitter, and completely inedible.
