"That's great! I can also learn more skills from Brother Yu!"
"Little Tail" was happy for his brother to have such good luck, but at the same time he felt a little regretful that he had missed so many good opportunities by just snoozing.
Shang Wu saw the slight discomfort in "Little Tail"'s insincere praise, so he gently tugged on her sleeves, smiled at her, and made a beautiful "orchid finger" with his hand. The dancing posture hinted to her: "Girls! Don't always want to be strong. Dancing with swords and guns is the strength of boys after all. Sister, I just need to teach you how to dance."
How smart "Little Tail" is! Of course she understood, and she smiled sweetly at Sister Shang Wu, and instantly put away the slight feeling of frustration just now.
Xiang Zhong was completely indifferent to these child-like "worrying about gains and losses". All his thoughts now were on Li Dan and his "Yue Xin Zhai".
"May I ask Brother Dan? Where did the name of this bookstore come from?" Xiang Zhong knew that he was the focus of the guest today, so naturally he couldn't be too polite and restrained, wasting such a rare opportunity.
"Everything in the world, everything you see, hear, smell, taste, and touch, all have sense organs. Only this 'self-mind' is the most difficult to understand, and there is no way to start reading it. I studied under Shang Rong, and a doctor once taught me. To save my lesson, I try to live in this house and read the books of the world’s sages. It’s hard to calm down my mind after reading it, so I named myself ‘Yu Xin’. There is no other, that’s why!”
When Li Dan talked about the origin of his name, he showed his persistence in exploration. It can be seen that the "everything in the world" he mentioned includes himself, and the most difficult thing to understand and understand clearly is his own understanding of himself.
"So, how is it easier to 'read one's own mind' or 'read another's mind'?" Xiang Zhong then asked.
"I read my own heart, naturally; I read other people's hearts, where do I start?" Li Dan answered with a smile. This kind of "ordinary person" answer made Xiang Zhong feel forced to "take the move", " The hole you dug has to be filled by yourself." It feels like it's self-defeating.
"I wonder if the 'heart' I am talking about and the 'heart' written in the name of Brother Dan's study can be the same as the 'heart'? If it is the heart of flesh, it can be seen if it is dissected; if it is the heart of thinking, it is useless to dissect it."
Xiang Zhong feels that starting from physiology class is not too far-fetched!
"The heart of flesh is simple, which can be seen in the massacre; the mind of thoughts is intangible, and careful study is futile. Therefore, the intangible mind of thoughts is the most difficult to read."
Li Dan replied seriously, as if he didn't seem to think that Xiang Zhong changed the topic just now and had any purposeful motive for a funny prank.
"I would like to ask you again: Use your own invisible heart to read the invisible hearts of others. Is this heart that reads hearts located in the head, chest, or belly?"
Xiang Zhong really wanted to know what people were thinking about this problem, so he took this opportunity to discuss it clearly in front of Li Dan.
"Human beings are born in nature, and the same principle applies to nature: thoughts are like the wind. The wind is invisible and comes everywhere. No matter mountains, rivers, huts, or ravines, it goes everywhere and is everywhere. Therefore, the 'thinking mind' of a person is also not fixed. There is no place where I live, no matter what I feel, that is not where I think, and there is no place where I am not thinking.”
Obviously, Li Dan's first association with the matter of "invisible" is "wind": among the celestial phenomena such as wind, cloud, rain, snow, and fog, wind is indeed the most intangible. It is really useful to use it as a metaphor for the "thinking mind" of adults. You have to be clever!
Seeing that he was just trying to make things more concrete, but Li Dan turned a scientific problem into a philosophical proposition with just a burst of "wind", Xiang Zhong felt that it was still necessary to "popularize science" for him.
Xiang Zhong touched his pocket, took out a pecan, and cracked open the shell, revealing the pulp in the middle that looked like a human brain.
"I have a method that can give me a glimpse of people's 'thoughts'. Like a walnut, a mortal's mind can be divided into two halves: the left and right halves: and then divided into five parts: the 'frontal lobe', the 'temporal lobe', 'limb', 'parietal lobe' and 'occipital lobe'; the first 'frontal lobe' is responsible for thinking, decision-making and advanced cognition; the second 'temporal lobe' is responsible for hearing, language and short-term memory; the third 'limbic' is It is responsible for long-term memory and emotion; its four 'parietal lobes' are responsible for various body sensations: such as touch, taste, and space; its fifth 'occipital lobe' is responsible for vision. The combination of these five is the brain; and the cerebellum below it The brainstem is responsible for breathing, heartbeat, and balance. People's "thinking mind" is just the function of this organ, such as the hand can hold a cup and the foot can jump. All ordinary people have thousands of thoughts from this, Whether it is foolishness or wisdom, it all arises from this.”
Xiang Zhong slowly broke the walnuts in his hand into several pieces one by one, and ate them while introducing them. When he finished talking about them, all the walnut kernels were eaten. In his hand, there was only a pile of broken walnut shells, which were gently placed on his mat.
"Brother Zhong'er, why did you eat them all! My 'temporal lobe' is not enough, the other 'leaves' are all about bleating... I haven't remembered it yet! It's so impressive!"
"Little Tail" originally said that she would not say anything out loud, but she was only thinking about the common sense of foodies such as "eating walnuts must break the walnut shells", but she did not pay attention to the functional divisions of each brain that were just demonstrated to Zhong. , only remembered one "temporal lobe" in charge of short-term memory, so she had to repeat the only new word she remembered.
In fact, it's not just her who didn't remember it. Everyone here except Li Dan didn't remember it completely. They were all shocked by Xiang Zhong's operation.
Although everyone usually eats pecans, no one has ever pointed to this small dried fruit and made it clear that it contains the ultimate secret of the human brain.
"Master Xiang is so familiar with it, have you ever seen someone's brain in person? What is the basis for such an explanation?"
Li Dan was extremely smart. Although he had memorized everything, he still had a series of question marks in his mind. He was half-convinced about the functional divisions just mentioned by Xiang Zhong.
Xiang Zhong knew that he couldn't explain to them that this was common sense from the "biology class" of students thousands of years later, so he had to pretend that "the secret cannot be leaked". It was taught by gods and men in his dream last night, but he was not allowed to He named the man of God. Since he had promised, he had to fulfill his promise, including the promise in the dream.
"Surely, if we are destined, can we also expect to receive this divine instruction in a dream?"
Ji Yu was addicted to becoming a disciple. He slept less and became a disciple of Chang Zong, but missed the opportunity to share the same pillow, sleep and dream with the god and teach him the miracles of the human brain.
"Brother Yu, you all know it's fate! It's a chance you'll meet, so don't think about it any more!"
Shang You snickered and pretended to be serious to comfort Ji Yu.
"However, as Xiang Gongzi said, this fleshy human brain is the 'flesh heart'; and the 'thinking heart' is also born from the 'flesh heart', so when a person lives, he thinks about his actions; when he dies, he thinks about passing away, right? ?”
Li Dan was not interrupted by other people's interruptions. He continued to study deeply. This was very "scientist spirit" and was something Xiang Zhong respected very much.
"Normally this should be the case. However, if this 'thinking' is not only born in a certain 'flesh heart', but is born in thousands of 'flesh hearts', then even though the thousands of flesh hearts are dead, the 'thinking' is still alive. Eternal life can grow and change into more 'thousands of fleshy hearts'."
Xiang Zhong answered seriously.
"What you said to Mr. Xiang means: can there be an impermanent 'flesh heart', but can there be a permanent 'thinking heart'? Is there any more explanation?" Li Dan started to listen, and he felt "motivated" and couldn't stop. The ground continued to ask.
