Wogan is not an orange, but a late-maturing hybrid citrus fruit obtained by crossing "Tempu" orange and "Danxi" red orange, so Wogan combines the advantages of both and has the characteristics of two oranges.
Vogan should choose skills.
Look at the color: the mature Vogan should be orange-red and look shiny. Try to avoid choosing other colors, such as cyan, which are probably immature oranges.
Look at the fruit base: when we usually buy it, we see that the fruit base of Wogan is convex, which means that Wogan is not ripe yet. This kind of Wogan will feel sour and slightly sweet when eaten in the mouth. The pedicel of naturally mature Vogan should be flat or concave.
