After Li Changqing instructed the children in calligraphy, he returned to the cabin at the foot of Zhongnan Mountain.

Since he accidentally got a hundred-year-old lightning strike sycamore wood on the mountain, Li Changqing has been practicing his qin skills hard and has made dozens of lyre.

There are hundreds of steps involved in making a lyre, each of which is very demanding, and any subtle factor may affect the timbre of the instrument.

Li Changqing took out a piece of catalpa wood from the wooden house where the miscellaneous family was stored, carried the cowhide bag to the grass shed, took out the wooden frustration knife, wooden chisel, planer knife and other tools, and skillfully transformed the catalpa wood into the body of the piano, with seven steel wire strings, a lyre is complete!

It is not only the craftsmanship of the piano that you need to be perfect, but also the material of the wood!

A hundred years of lightning strikes plane wood, can be met but not sought, is an excellent wood for the qin.

Li Changqing warmed up by making catalpa xylophone, adjusting his body and mind to the peak state, holding the century-old lightning plane tree that he had treasured for a long time.

The upper part of the sycamore wood is charred, similar to the scorched tail of the four famous harps.

Li Changqing tapped the sycamore wood with his fingers, and a melodious and tactful voice came out.

It is recorded in the "Book of Music: The Method of Chopping the Qin": "Where the bottom is thick and thin, the wood is turbid and clear, the big strings are dull, and the small strings are scorched." The bottom of the surface is thick, the wood is solid, and the rhyme is short and the sound is focused. The surface is thin and the bottom is thick, and the wood is weak and green, which is conducive to small strings and not conducive to large strings. The bottom of the surface is thin, the wood is empty, its sound is bursting out, and the sound rhyme is wafting ....... ”

Li Changqing struck the sycamore wood to listen to its sound, in order to test the sound quality and vibration degree of the wood itself, and to infer the thickness of the abdominal cavity of the piano panel.

After making preparations, Li Changqing carefully planed the plane tree in the hundred-year-old lightning strike, and it was only in the evening that it had a prototype.

In the early morning, Lijiaao was very lively.

Li Changqing continued to read "Shang Xian", and the response was very strong among the audience.

Ning Cailing, editor of the WeChat public account of 'Guyang people' in Guyang, gathered a group of young people to organize Li Changqing's words and deeds into text and upload them to news and social channels such as Tieba, public account, and Weibo, which attracted many lovers of Chinese culture on the Internet and spread Li Changqing's voice further.

The text is a little pale compared to Li Changqing's reading voice, but it can still have some effect.

Li Jiaao Primary School is about to hold its final exams, and Li Changqing went to the mountains to continue playing the piano after talking to the children after reading the book.

Two days later, Li Changqing sat in the bamboo forest, with an antique lyre flat in front of his lap, the body carved into a phoenix flying for nine days, and the black part of the sycamore wood happened to be the position of the phoenix's tail.

"In ancient times, there was Cai Yong's Jiaowei Qin, so you called it Fengweiqin!"

Li Changqing's fingers swept on the strings, and the sound of the piano sounded like a birdsong in an empty mountain, and he smiled.

Huan Huanxi was sleeping soundly in the sun, but after hearing the sound of the piano, he pricked up his ears and stared at the phoenix tail qin in front of Li Changqing.

Many people under the mountain can't Li Changqing, glory, wealth, fame and fortune are at their fingertips, but they live on the bitter cold Zhongnan Mountain.

Li Changqing drank monkey wine and played "High Mountains and Flowing Water", one of the top ten ancient Chinese songs.

Halfway up the back mountain, Chen Yaru and He Guangyao were walking on the mountain road.

"Yaru, did you hear the sound of running water?", He Guangyao asked.

"It looks like someone is playing 'Mountains and Flowing Water'!"

Chen Yaru wore a black sportswear and a peaked cap, and listened carefully.

"There is only one person in the mountain, could it be Mr. Li?", He Guangyao wondered.

"It should be, who would have thought that in addition to being proficient in Chinese studies, mathematics, medicine, and feng shui, Mr. Li would even reach the peak of his piano skills!"

Chen Yaru has learned the guzheng, which has similarities with the lyre.

"Hehe, come and send a jade ruler to Mr. Li, and I actually heard the peerless piano sound!"

He Guangyao was intoxicated by the sound of the piano and said with satisfaction.

"Mountains and rivers are high and rivers are hard to find! What kind of person is he, will he agree to his request?"

Chen Yaru's impression of Li Changqing is as elusive as a breeze, and she can't help but feel a little bit like a little daughter in her heart.

"Yaru, it's rare to see you have a nervous mood, do you fall in love with Mr. Li?", He Guangyao quipped.

"Uncle He, what are you talking about......", Chen Yaru's face blushed, and she unconsciously quickened her pace.

"If Mr. Li can see it, things will be easier!", He Guangyao thought to himself.

When I arrived at the grove, the sound of the piano was nearing the end, like the deepening of the flowing water, like a filament, like the murmur of a milk swallow, like a cricket whispering, and then merging into a whirlpool, swimming farther and farther away, until occasionally hearing a beautiful melody.

"Uncle He, how do we get in?", Chen Yaru said.

"It's dangerous to break into the formation, let's shout and try!", He Guangyao said.

"Uncle He, come and shout!", Chen Yaru said.

"Okay, Mr. Li, I'm He Guangyao, I owe you a jade ruler in the last competition, and I specially sent it to you!"

He Guangyao clasped his hands together as a megaphone and shouted into the grove.

"Go!", Li Changqing vaguely heard He Guangyao's voice, and made a gesture to Huan Huanxi, who immediately rushed to the grove.

Huan Huanxi and Li Changqing left their body fluids in each position when they walked around the grove, sniffing their own smell, and soon ran to the entrance of the grove, making a 'sneer' sound at Chen Yaru and He Guangyao.

"Hey, two fluffy weasels, they look so cute!", Chen Yaru looked at Huanhuan and said happily.

"Look at their smooth fur and shiny eyes, they may be Mr. Li's pets!", He Guangyao said.

"Uncle He, are you saying that these two weasels were sent by Mr. Li to pick us up?", Chen Yaru said in surprise.

"Well, it's very likely!", He Guangyao said.

"That's right, it won't be strange if anything happens to Mr. Li, so let's follow them!", Chen Yaru said.

He Guangyao and Chen Yaru followed Huan Huan Xi closely, and finally appeared outside the cabin with a bright eye, and saw Li Changqing sitting in the bamboo forest in white clothes, with a straight guqin in front of him, and Huan Xi rushed to Li Changqing to squat on both sides.

Chen Yaru looked at the simple environment of the cabin, and finally stopped her eyes on Li Changqing, and she actually felt like she was in a different world.

"Mr. Li, this jade ruler is a relic of the famous feng shui master Wang Lutan of the Qing Dynasty, and it is also a pearl in my hands, and it is just transferred to you!"

He Guangyao presented a jade ruler like mutton fat, with a bell scale engraved on it.

The jade ruler is generally used to measure the mountain direction, three-dimensional coordinates, landscape vision, ecological environment, topography and other factors related to feng shui, the ups and downs, the size of the high, the good and the bad, the prosperity and the decline, Wang Lutan is a master of feng shui in the Qing Dynasty, and the jade ruler he used is naturally very valuable.

"You're not just here to bring me a jade ruler!", Li Changqing said.
