I have learned to turn my tongue without saying anything.

The river water in China is clear.

And the summer day is long,

There is no need for a long time to fill the pond.

----------------------

The summer is the most lush vegetation, and the sun is burning on the top of your head, but it still resists the magnificent scenery of China.

The mountains and rivers are particularly popular at this time. In the deep forests, the mountain breeze blows through my ears, and sometimes I will unexpectedly feel like I traveling through autumn, and I feel a little chill.

The greenery all over the mountains is not only the umbrella-like shade, but also the treasure house of water. The rainfall that falls in the mountains all year round has long been sucked away by trees.

Now that the sun is so full, they may die if they lose water like them, so they turn into "hydration sprays" one by one, spraying the water accumulated before rhythmically out of the vents to replenish the water coming and going.

"Child, do you know a parrot that can learn to learn tongue?" An old man sat in a pavilion built by the aisle for tourists to rest, talking to his granddaughter.

The granddaughter next to him nodded, "Well, I know, in many videos online, those parrots will still quarrel with their owners!"

"My granddaughter knows so much!" The old man gently scraped his granddaughter's little nose with his hand, "So smart!"

"Today, Grandpa wants to tell you a bird called "Talkback"."

"What about mockingbirds? I want to say that they are a bird that can learn tongue..."

"Like a parrot?"

"Yes, like a parrot, you can learn all kinds of other sounds."

"When it comes to the third phase of the Mangsei, the mockingbird feels the "yin energy", so it stops coming out, and there is no longer a bird that learns tongue on the branches!"

"Grandpa, what is "yin energy"? Is it the kind of coquettish thing in ghost stories?"

"No, Taoism believes that "yin" and "yang" are mutually generated and restrained... By the way, you have seen the equipment used by grandparents who played soft balls and Tai Chi in the park in the morning, and the Tai Chi diagrams drawn on the shoes they wore?"

"Um!"

"That is the yin and yang of the painting. These two are fertile, which are completely opposites and are inseparable."

"Grandpa, is this metaphysics?" The child said, while standing up with his grandpa and continuing to climb to the heights of the mountain.

"No, our Chinese Taoist theories are not strange powers and chaotic spirits, but ancient simple materialism! It is a serious philosophy." Grandpa said with a smile.

"Philosophy...what is that?"

Although my grandfather was old, my granddaughter was still very young and was pulled by my grandfather, but I couldn't follow my grandfather's pace, so I had to chase after him, jumping and jumping.

Seeing this, the old man slowed down, looked back at his granddaughter, and walked slowly forward.

"Is it philosophy..."

"Philosophy is a smart science!" As he said that, the old man picked up his granddaughter and continued, "When you grow up, you will learn it. If you want me to tell me, the philosophy of our Taoist theories can keep up with the times!"

Obviously, my young granddaughter can't understand words such as "philosophy", "Taoist theory", and "materialism", and I'm afraid I have to wait until I go to high school to truly get in touch.

The old man didn't care whether his granddaughter could understand or not. He also talked about other knowledge while walking. When the old man's granddaughter grew up, he would sigh that his grandfather was very knowledgeable!

As for Jiuzhou and Mangzhong, it was so uncomfortable to travel around the mountains and rivers. The heat these days made Jiuzhou a little irritable, and now it was swept away by the water mist with the cold air in the mountains and forests.
