How to divide oranges into male and female
Oranges are divided into male and female, the male is not delicious, and the female is delicious.
Distinguish the sexes of oranges. Look at the end of the orange, not the end of the leafy branch, and see if it is a circle with a cross in the middle or a black spot. The circle is female, delicious; The black spot is male, which is not delicious. Also, pinch it to see if the skin is too thick. Thick skin is not delicious. Also, look at the single weight, heavy water is more delicious, and light water is less delicious.

The most important thing is to weigh it by hand, which is both heavy and good. The same orange is a heavy proof of its freshness.
3, look at the bright color and a circle of concave points around a small point, which is sweet. 4, pick the kind of "navel" flowering, the bigger the flower, the better.
