After several days of picking up garbage in popular attractions, not only the adults worked hard, but even Jiang Che lost a lot of weight.

Yan Ming is happy to love Mengmeng, and invites him many times to hide in the shooting car, but Mengmeng firmly refuses.

The staff all admired this kid with amazing tenacity and endurance.

Looking at the backs of the family of three, I inexplicably feel that they are like a shadow, very similar in their bones.

Unknowingly, the itinerary of picking up trash is about to turn over, and everyone came to the last stop.

They came to the quiet primitive area again. Looking at the vast grassland through the car window, occasionally a few cute Przewalski's gazelles flash past, like small white stripes in the waves, and like shooting stars in the vast universe.

Every time he saw the shadow of the Przewalski's gazelle, Jiang Che would excitedly tap the window: "Look, little gazelle!"

Hearing Mengmeng's guidance, adults can't help laughing.

Teacher Xiaofeng is also online in real time to popularize science for everyone.

The last stop is the Przewalski Conservation and Rescue Center.

The Przewalski's gazelle used to have the same ancestor as the Tibetan antelope. After natural evolution and migration, it slowly developed into a new species, the Przewalski's gazelle.

However, at the beginning, people did not distinguish between these two species, and it was later discovered that the Przewalski's gazelle has its own unique characteristics.

The Przewalski's gazelle is much smaller, with pale yellow undercoat in summer and nearly white in winter.

There is also a layer of white fluff on its underarm abdomen and buttocks. When encountering an enemy, the fluff on the Przewalski's buttocks will stand up and open like a flower to warn its companions.

Przewalski's gazelle is very ornamental when running. It is like an arrow that leaves the string, with the back foot kicking the front foot forward and leaping forward. When the front foot hits the ground, the back foot moves back, graceful and agile like a wave.

It is a herd animal, and it may be afraid of the heat in summer. It has always been full of a dozen or so and will not recruit new ones.

In winter, 30 or more, they gather together in large numbers, one is to keep each other warm, and the other is to fight against natural enemies in large numbers.

Of course, the Przewalski's gazelle has another characteristic. They are very particular about the difference between men and women. Except for the breeding season, boys play with boys and girls play with girls at other times.

In fact, Jiang Anzhi and the Przewalski's gazelle met each other in the first season of "Home Guardian".

The few poor lambs rescued by the poachers who needed gastric lavage, and the lambs sent out by Zhuang Nan and Li Yue, were the Przewalski's gazelle.

Przewalski's gazelle used to be a huge group, but because humans seized too much of their original living space, a large number of livestock preyed on them and had to withdraw to a barren place, so that it was difficult to survive without food and water. The wolf's attack killed a large number of Przewalski's gazelle.

All in all, the tens of thousands of Przewalski's gazelle have gradually decreased to less than 150, which is even smaller than the number of pandas.

According to this development momentum, the Przewalski's gazelle will be completely extinct within a few decades.

Therefore, the country listed it as a first-class endangered animal, and established a Przewalski Protection and Rescue Center in their habitat.

After rescue and cultivation by experts and scholars, the number of Przewalski's gazelle has now recovered to about three or four thousand.

After listening to Teacher Xiaofeng's introduction, everyone had a preliminary understanding of Przewalski's gazelle.

"I'm just throwing bricks and stones to attract jade. These situations and information are available on the Internet. The specifics will be explained to you when you see Teacher Ping."
