Mountains and rivers are high and watery, and bosom friends are hard to find.

Yu Boya, a native of the Jin Kingdom during the Spring and Autumn Period and the Warring States Period, was very good at playing the piano, and when he first met Zhongziqi at the mouth of the Hanyang River, he saw that Zhongziqi was a woodcutter and did not believe that Zhongziqi could read music and play the piano, so he asked Zhongziqi many special questions about instrumental music to test him. Zhong Ziqi's answer is like a stream, such as a number of treasures. But Boya still had doubts, so he plucked the strings tightly and played a song, wanting to test the Zhongzi period.

As soon as Boya finished playing the piano, Zhong Ziqi exclaimed: "It's beautiful, the meaning of the adult, in the high mountains." Boya played another song, and Ziqi praised again: "It's beautiful, and the ambition is to run water." Boya was shocked, pushed the piano up, and repeatedly gave salutes and accused, saying: "Disrespectful! There is a treasure of beautiful jade in the stone, if you judge people by their appearance, will you not live up to the wise men of the world?" and took the initiative to marry Zhong Ziqi as brothers with different surnames, and meet here again in the Mid-Autumn Festival of the second year.

In the second year, Yu Boya went to the meeting as promised, waited for a long time, and did not see Zhong Ziqi, only to learn that Zhong Ziqi had died of illness a few months ago.

Yu Boya suddenly "cracked in five hearts, tears gushed like springs, fell on the cliff, and fainted on the ground." After crying, Yu Boya stroked the piano in front of Zhongzi's grave and mourned.

After the lamentation was played, Yu Boya thought, from now on, there is no more ignorant sound, who will play the piano to? So he threw it hard and smashed the piano to smithereens, and later the story of "Boya fell the piano and thanked the bosom friend" was widely spread in history.

Yu Boya and Zhong Ziqi are both people in the Spring and Autumn Period and the Warring States Period, but Yu Boya is a doctor in the Jin Kingdom, and Zhong Ziqi is a woodcutter in the Chu State.

"This master of Chinese culture is on the top of the mountain, playing "High Mountains and Flowing Water", what a wonderful person!"

"Mountains and Flowing Water" is a famous Chinese song, Hu Yongping has never heard the qin music, but he knows the allusions, and he sighed with infinite emotion.

"Acquaintances all over the world, how many people can know each other? This master of Chinese studies has probably seen through the mundane world, so he lives in seclusion in the deep mountains and old forests!"

Kong Tianyi had the image of an indifferent and lofty wise man in his mind, the wise man had a childish face and kind eyes, and his eyes were as deep as the stars in the night sky, seeing through everything.

"Come in!"

Mu Zhengyang had already heard the footsteps outside the house, and after playing the piano song, he got three cups of tea on the table, and then said to the outside of the house.

Kong Tianyi and Hu Yongping were full of interest when they came, but they were a little apprehensive when they arrived outside the academy, "I will be able to meet that master of Chinese studies soon!"

The two pushed open the door of the academy, and there was a long table in the courtyard, and there was a simple guqin on the table, but the dragon head at the end of the guqin was vivid.

A young man with clear eyebrows sat at the table, wearing a white ancient rhyme practice uniform, with a faint smile on his face, giving people a feeling of spring breeze.

"You are a shepherd...... Mu Zhengyang?", Hu Yongping kept looking at the young man in front of him when he entered the door, and said after hesitating for a moment.

"Hehe, Mr. Hu, please drink tea!"

Among the two people who came, Mu Zhengyang knew the eldest of them, Hu Yongping, his Chinese teacher when he was a student in the county No. 1 middle school, got up and made a gesture to sit down.

Kong Tianyi and Hu Yongping sat down, but their eyes searched in the courtyard.

"Zhengyang, I didn't expect that there is a academy on this mountain, who are the people in the academy?"

Hu Yongping glanced around the academy, saw no figure, thought that the master of Chinese studies should be hiding, and asked sideways.

"Every day, except for one of my students, almost no one comes!", Mu Zhengyang smiled faintly.

"What about your students?"

Kong Tianyi spent a lot of effort to find the academy on the top of the mountain with Hu Yongping, and he didn't see the master of Chinese studies and asked unwillingly.

"My teacher is sitting next to you!", Mu Zhengyang smiled politely at Kong Tianyi.

"Don't laugh at it, although I have taught you, but I am just reading from the book! Your teacher who lives in seclusion in this academy is the real master!"

Hu Yongping hurriedly waved his hand, not daring to put himself on a par with the master of Chinese studies.

"Master?", Mu Zhengyang asked pretending to be puzzled.

"Zhengyang, the teacher of our county No. 1 middle school organized a team building activity in Tiannan Mountain yesterday, and when I climbed to the middle of the mountain, I heard someone reading on the hillside, not only did we immediately understand the meaning of the book after hearing the sound of reading, but even the birds and birds on the tree that were like a concert immediately quieted down! In my experience, the sound of reading must have such a magical effect must be a master of Chinese culture! To tell you the truth, Tianyi and I admired the demeanor of the master of Chinese culture and specially drove to visit! But I didn't expect you to worship under that master of Chinese studies, can you help introduce us to your teacher?"

The words were all said, Hu Yongping didn't hide it, and wanted to use the teacher-student relationship between him and Mu Zhengyang to let Mu Zhengyang match the bridge in the middle.

"Teacher Hu, I don't know if there is a master of Chinese studies in Tiannan Mountain, but if you are looking for the second peak scholar yesterday afternoon, that person should be me!"

Mu Zhengyang took a sip of tea and said in a slow tone.

"Haha, Zhengyang, when you were studying, it seemed that other subjects were among the best, but the language bias was quite serious! The major of the university is not Chinese, and even if you are a pen in the Chinese department of a famous university, it is 108,000 miles away from the master of Chinese studies!" Read thousands of books and travel thousands of miles, if you want to become a master of Chinese culture, in addition to being familiar with various classics, you must also have rich life experience, so that you can practice the realm of articles, but you are fortunate to worship under the master of Chinese culture, and now you are working hard to lay the foundation, and you may not have a day to become a real master of Chinese culture in the future!"

Hu Yongping expressed it very tactfully and implicitly, in fact, he was saying that Mu Zhengyang was too young, and his accumulation of knowledge and life experience were too far from the realm of a master of Chinese studies.

"If you were the one who read the second peak yesterday, then you were the one who played the piano on the top of the mountain just now?"

Kong Tianyi very much agreed with Hu Yongping's statement, Mu Zhengyang was far from the master of Chinese studies he envisioned, and asked again.

"Hmm!", Mu Zhengyang nodded.

"Then you are not only a master of Chinese culture, but also a master of guqin playing?" Kong Tianyi asked deliberately.

Mu Zhengyang didn't answer Kong Tianyi, he stood up from the table and stood with his hands in his hands, taking a step in the courtyard every time he read a book.

"The heart of compassion is the end of benevolence, the heart of shame, the end of righteousness, the heart of resignation, the end of courtesy, the heart of right and wrong, and the end of wisdom. The reason why the gentleman teaches is that there are those who are like the rain of the times, those who become virtuous, those who reach wealth, those who answer questions, and those who are selfish. The reason why the gentleman teaches these five is also ......"
