"Sister, Yuanmou people appeared 1.7 million years ago, and Zhoukoudian people in Beijing were 700,000 to 600,000 years ago. The difference between the two is about 1 million years!"

"One million years!" My sister looked at me in surprise, "The primitive people are really useless. You see, we humans have become so advanced in just five thousand years. If you give us a million years, I think You can travel the galaxy!"

Well, I will stop talking, it seems that my sister has absolutely no concept of the history of human evolution.

It is estimated that in her mind, apes, primitive humans, and current humans are three unrelated species.

In other words, in her opinion, it was the primitive man who defeated the ape-man and won the dominance of the earth, and then the current human being defeated the primitive man and became the new master of the world.

I don't speak, it doesn't mean my mother doesn't speak.

"Silly boy, you can't count like this!"

With an unstoppable smile on my mother's face,

"Then dinosaurs have ruled the earth for hundreds of millions of years. They have been drinking blood for hundreds of millions of years. Can you explain that they are useless?"

"Dinosaurs are useless!" My sister pouted, "The dinosaurs you watch on TV are like two fools, they only know whether to run or roar when they chase their prey, but don't know how to use tools? ?"

"Hahaha……"

I finally couldn't help laughing.

There are quite a few people in the restaurant now, so my sudden laughter didn't get much attention.

"Am I wrong?" My sister looked at me seriously.

"No, exactly!" I gave my sister a thumbs up with both hands.

The mother sighed with a helpless smile on her face. She has decided to give up the "rescue" of this daughter.

After a while, the waiter came over with three disposable paper bowls.

"Your little noodles, please use it slowly!"

After we thanked each other one after another, we started our own way.

My sister has a very strange habit of eating noodles. She never eats soup or vegetables. In her words, when you eat noodles and noodles, what you eat is noodles. What do you do with soup and vegetables.

So, the first action my sister took with her chopsticks, she was going to pick out all the vegetable leaves in the bowl and give them to me.

Looking at the vegetable leaves my sister picked up, I quickly put my hand over the mouth of the bowl, and shook my head at her with a serious expression.

"You must eat vegetables!" Mom took the vegetables from my sister with chopsticks and put them back into my sister's bowl.

"Oh, I don't want to eat it!" My sister muttered and stirred in the bowl, "The human cecum has long since degenerated, and it can no longer digest plant fibers, so why eat vegetables!"

This is a biomedical problem, and it just so happens that my sister is a medical student, so her explanation can seem so professional.

"Then do you know that although we can't digest plant fiber, plant fiber can promote our intestinal peristalsis and help digestion!"

"Of course I know this!" The elder sister looked at her mother speechlessly.

"Then you don't eat vegetables!"

...

...

In the end, whatever I said, my sister probably thought that my mother was too ink, so she reluctantly ate the vegetable leaves.

After eating the small noodles, my mother settled the bill, and then we left the noodle shop.

"Where are you going now?" Mom asked while holding the ticket in her hand.

"Buy some water first, you will die of thirst!"

My sister held my arm with one hand and my mother's arm with the other, shaking it gently.

"When you say that, I also feel a little thirsty."

Saying that, my mother turned her head to look at the small shop next to her, and then pulled her sister, who pulled me, and walked to the canteen!

After one person bought a bottle of water, we wandered aimlessly in the playground.

Standing at the bottom of the sky, watching the tourists screaming because of free fall; standing on the site of the bumper car, watching the tourists driving each other; A tourist who flew out...

All kinds of laughter and laughter continued, so that people like us who were watching the fun couldn't help laughing happily.

After walking around for a while, we walked into the zoo area again.

My sister shouted to go to Monkey Mountain to see the monkeys, so we went too.

There are quite a lot of monkey species in Monkey Mountain, such as golden monkeys, dolphin-tailed monkeys, green monkeys, white-nosed long-tailed monkeys, macaques, red monkeys...

"They're all monkeys, why are they divided into so many species?"

This is the question that my sister couldn't help but ask after looking around.

In fact, I really admire these people who give names to monkeys. Every species of monkey has to have a name. With so many names, isn't it hard to remember?

Suddenly, I feel sympathy for those students. An outline is divided into sub-categories. When I see a species, I have to distinguish it from some subtle points. It really hurts.

My sister's second question was, "Why are monkeys' butts all red?"

It's a weird question, and my answer is: because they don't wear pants, they don't have hair on their butts, and they're sunburned.

Of course, this is just a funny Q&A between me and my sister. As for why the monkey's **** is red, I don't know.

After leaving Monkey Mountain, we stopped by to see the gorillas.

While watching gorillas, I came across an interesting thing.

A tourist threw a walnut in, and then a gorilla who was scratching the lice climbed over, calmly picked up the walnut on the ground, and ran back and smashed it with a stone.

This gorilla can actually use tools, it's almost like he's going to be fine.

"Brother, you said if I throw this bottle of water in, will the gorilla unscrew the bottle cap and drink the water!"

Seeing my sister holding a water bottle and eager to try, I was taken aback by her, and I hurriedly reached out to stop her,

"Don't, don't, it's very unethical to throw things at the animals in the park indiscriminately. If the management of the zoo sees it, they will be fined and may be driven out."

"The one who threw the walnut just now..."

Forehead……

"He is him, we are us."

"Okay!" My sister gave up her plan to throw the water bottle in to test the gorilla's intelligence.

My mother has been watching, always with a smile on her face.

Although the temperature today is not too high, it is unrealistic to say that there is no sweat after walking for so long.

After coming out of the gorilla park, we found a place to sit for a while, then took a breath and walked towards the tiger and lion pavilion.

These two animals are what my sister is looking forward to the most. When watching "The Fantastic Drifting of Young Pi", my sister likes the wild tiger very much.

Unfortunately, the tiger in the zoo disappointed her.

Where is this tiger? It's like a pig. It either eats or lies motionless on the ground. It's too lazy to die. How can there be a trace of the demeanor of the king of the forest!

"It's not like the tigers on TV at all. Forget it, let's go to see the lions!"

"The lion is probably not much different!" I couldn't help shaking my head gently, "You, it's better not to have too many expectations!"
