It’s orange season again! Which one is your favorite?

As autumn deepens, a large number of oranges are freshly available on the market. With their sweet and sour taste and rich juice, they have become one of people's favorite fruits in autumn and winter.

In such a beautiful season, you can lie down on the sofa and pick up a sweet tangerine to relieve your fatigue and immerse yourself in a rare relaxation.

However, I wonder if you have noticed an interesting detail. There are countless varieties of tangerines on the market, such as sugar tangerines, honey tangerines, and tribute tangerines. But what are the differences between them as tangerines? And what is the relationship between fruits such as oranges and lemons and the tangerines we often talk about? Please follow us to explore the love and hate of the tangerine family!

The first thing we want to talk about is the difference between tangerines and tangerines. The original meaning of "ju" is pronounced as "jie" (second tone), which is a colloquial word for "ju". It can be used for both when pronounced as "ju" (second tone), so tangerines and tangerines are essentially the same thing.

Next, let’s start with the eldest brother of the Orange family.

Research shows that the ancestor of citrus plants was a plant that lived in the Himalayas 8 million years ago. Later, due to the disappearance of the monsoon from the ocean in the Himalayas at that time, the ancestors of the citrus family were forced to walk down the mountains and launch an expedition to the land.

The Orange boss divided his troops into three groups, expanding the territory to the east, west and south respectively, laying the foundation for the establishment of the Orange Empire with its complicated relationships.

The branch heading east evolved into two small branches - orange and kumquat; the branch heading west evolved into the "regent" of the citrus family - citron; the branch heading south was not to be outdone and sent out General Pomelo to compete with citron.

It was not until 2 million years ago that the broad-skinned orange came to power, and the citrus family officially entered a three-way balance of power.

The orange family has also forged a deep bond with humans in its continuous evolution. Not only were they given to each other as red envelopes by ancient Chinese ancestors as blessings of good luck, they have also been endowed with rich medicinal and commercial value.

Under the unremitting pursuit of deliciousness, new varieties such as sugar orange, tribute orange and honey orange have been cultivated, making the orange empire continue to grow and making our lives more colorful. The following is a graphic illustration of the kinship history of the orange empire.

So the story about the Orange Family comes to an end. I wish everyone who reads this will be prosperous in life and all their dreams will come true!
