The side door of the temple of the saints is open, passing through a long corridor filled with calligraphy and paintings.

It is an antique room, and the plaque reads 'Mingde Hall'.

There is a portrait of Confucius hanging in the main hall, with an elm table of eight immortals under it, and a chair on the left and right.

"Congratulations to Brother Li, entering Mingde Hall. Yan Hui came over from the other side and congratulated Li Changqing.

"Hehe, I'm wondering, I'm going to come here with my feelings!", Li Changqing said with a smile.

"Brother Li's appearance here shows that he has studied the essence of the Four Books and has passed the enlightenment stage on the road of Confucianism!"

"The teacher taught well, and Brother Yan gave him many instructions. ”

"Brother Li will make rapid progress only if he is diligent, and he can proceed to the next step of learning. ”

"After reading the Four Books, is the Pentateuch next?"

"Only half of the guesses are correct, in fact, there are six scriptures in total. Yan Hui took out six thread-bound books from his sleeve.

"Hey, there is also a copy of the Book of Music!", Li Changqing took Yan Hui's book and said in surprise.

Among the thick books, Li Changqing has a slight understanding of "Poems", "Books", "Rites", "Yi", and "Spring and Autumn".

However, the "Book of Music" has a bad fate and has been lost for a long time, and Li Changqing only heard about it when he was looking for information.

"Yes, in addition, Brother Li can get a new reward for completing the Four Books Quest, the Nine Palaces Academy. Yan Hui continued.

"Nine Palace Academy?"

"You can practice calligraphy and painting in the inkstone pond, and the Jiugong School Hall is a place to learn mathematics. ”

"The six arts of Confucianism, music, archery, royalty, calligraphy, and mathematics, do numbers refer to mathematics?"

"Not exactly, now it has been extended to the number of mathematics, physics and chemistry. ”

"Do you have any requirements?", Li Changqing asked after knowing the routines of the Hundred Schools of Thought.

"You only need to be proficient in the number itself, but the chess skills derived from the number must reach the pinnacle. ”

"Is there still a place to practice chess skills in the Nine Palaces Academy?"

"That's right, there is a Tianyuan chess room in the Nine Palaces Academy, and there are many rare chess games. ”

Yan Hui said and took Li Changqing from Mingde Hall to the Nine Palace Academy.

The Jiugong Academy is a courtyard of blue bricks and gray tiles, and the west chamber hangs a sign of Tianyuan chess room.

There were many professional books on mathematics, physics and chemistry on the shelves on both sides of the main hall, and Li Changqing didn't know where to start for a while.

In the Tianyuan chess room, there are ancient books such as "Treatise on the Book of Chess", "Dream into the Divine Machine", "Plum Blossom Spectrum", etc., and an old man in a navy blue coat sits in front of the chessboard and nods to Li Changqing.

"Hello, old sir. Li Changqing stepped forward and greeted.

"Young man, are you here to learn how to play chess?" the old man asked.

"Uh-huh!", Li Changqing nodded.

"The old man, Fan Xiping, is responsible for managing the Tianyuan chess room. ", the old man said with his beard brushed.

"I'll trouble the old gentleman in the future!", Li Changqing said to Fan Xiping.

Li Changqing just walked around the Nine Palaces Academy and quit the game of Zhuzi Hundred Schools.

There was a light rain in the sky, and the mountains of Zhongnan Mountain were very wonderful.

Li Changqing stood under the grass shed and listened quietly to the sound of the rain, smelling the moisture in the air and feeling refreshed.

After the rain, the bamboo leaves are so green that they want to drip water, and the delicate orchids are like beauties who have just come out of the bath without causing dust.

Li Changqing hugged the "Book of Music" given by Yan Hui, and wanted to explore what was written in the Book of Ancient Wonders.

"Every sound arises from the heart of man. The movement of the human heart is also made by things. ”

"Feel the resistance of things, and let go of sound. The sound corresponds, releases and changes, and becomes square, which is called the sound. ”

"It's more fun than music, and it's fun to be in Qi Yuyu. ”

All music originates from the human heart. People's inner activities are the result of being influenced by external objects.

The human heart is agitated by the influence of external objects, and thus expressed through sound. The various sounds correspond to each other, and from this change comes a change into an orderly order, which is called a sound. The combination of music for playing and singing, and the dance with props and feathers, is called music.

"Musicians, where the sound is born, its origin is in the human heart, and the feeling is also in the object. ”

Therefore, those who are sad and feel their hearts will be killed with their voices, those who are happy will be slow down, those who are happy will be scattered, those who are angry will have their voices coarse, those who are scattered will have a straight voice, and those who are happy will have a gentle voice. The six are non-sexual, and they move after feeling things.

It is believed that music is generated by sound, and the origin of its production lies in the fact that the human heart is moved by external objects.

Therefore, when there is a sad feeling in the heart, the voice is rapid and low, when the heart produces a happy feeling, the sound is stretched and gentle, when the heart produces a joyful emotion, the voice is uplifted and unrestrained, when the heart produces angry emotion, the voice is rough and agitated, when the heart produces the emotion of reverence, the voice is solemn and upright, and when the heart produces the feeling of love, the voice is gentle and gentle. These six emotions do not arise from human nature, but are stimulated by external objects.

When I read the music book, Li Changqing was greatly moved!

A book of music not only points to the essence of music, but also tells how to use music to subtly influence people's hearts.

If the "Book of Music" can be handed down and carried forward, what kind of scene will it be now?

Li Changqing watched "The Book of Music" so drunk that he even forgot to eat and sleep.

It wasn't until the little squirrel came back from the mountain and jumped on Li Changqing with a nut that Li Changqing found that it was still night.

Huan Huan Xi also crawled out of the basket and fell to the ground, his eyes moistened with pity.

Li Changqing carried Huanxi back into the basket and began to soak them in milk.

After taking care of his father's work, Li Changqing looked at the cool moonlight and thought about whether he should make a guqin.

Close your eyes and listen to the sound of the wind blowing the bamboo leaves, smell the fragrance of orchids, and become one with your surroundings.

Playing the piano under the moon with his bare hands, the beautiful melody echoes in the valley.

However, the coming days are long, and Li Changqing is not in a hurry.

Li Changqing, as usual, went to Lijiaao Primary School to lead the students to read and sell leeks, and Gao Xiaojun, Pan Yuting, Wang Zhuyun and others also joined the reading team.

"Chinese culture and painting are both unique, but their reputation is not obvious, and they are really masters in the people!"

After Gao Xiaojun finished reading it, he remembered that there was a painting in Li Changqing's painting yesterday, and he couldn't help but sigh.

"Professor Gao, are you still in the mountains today?", Li Changqing came over and asked after selling leeks.

"Collect all the drafts of Qifeng, and Principal Li will naturally go if it is convenient. Gao Xiaojun said very politely.

"Well, let's go now!"

Although Li Changqing has a bamboo forest and an inkstone pond, he also wants to experience the feeling of orthodox academics.
