"Professor Guan, can you show us that?" the moderator asked.

"No problem. Guan Zhijun took out a D-tuned suona with a live core installed, and said: "Here is its inner tube, which is connected with an air card and a gas noveil, as well as a bolt groove, and a spring on the outside, so that it can be retracted." It can be inserted directly into the outer tube and is easy to disassemble. It does not change the structure of the traditional suona, but only replaces the original copper core. It can be matched with any brand of suona, no need to buy a musical instrument, you can use it when you replace it. When using it, use the lips directly to compress the air nozzle, so that its inner tube shortens its interval, so that it can blow semitones in each sound hole. This can not only increase the volume range of suona, but also play a variety of pitch-changing music that traditional suona cannot play. The performer can not only play traditional techniques, but also improve the player's ability to play semitones, complex key transitions, and large portamentos. ”

"What you said is too professional, I believe that many audience friends in front of the scene and TV are like me, I didn't understand, why don't you teach you to play a piece for us on the spot?"

"Okay, I'll play a traditional suona song "Six Characters Open the Door", I will blow twice, first blow once with traditional techniques, and the second time will use the technique of chromatic and tonal transformation, everyone listen and see if you can hear the difference. ”

With that, he went to the center of the stage, blew two segments, and the scene cut to the audience, giving the audience a few seconds of applause.

"Hey! This shameless version of the variation is not a shame to perform on stage without being proficient!" Liu Wanxiang looked at the picture of Guan Zhijun on TV, gritted his teeth and said hatefully.

"Anyway, no one can hear it, and a few pitch-shifting notes are enough for him to prove it. ”

Cao Wu looked at Guan Zhijun on TV and said.

He investigated this Guan Zhijun and found that this was really not a simple guy.

He was a high-achieving student who graduated from the Wind Music Department of the China Conservatory of Music in the late eighties, and was hired to teach by the Music Department of HD Normal University after graduation, but within a few years he caught up with the reform and opening up.

He had a good brain, made a lot of money, and lost a lot of money during the financial crisis of '98. After the millennium, he went to ZJ Province to open a furniture factory, made a comeback, and prospered for a few years, but because of divorce and a lawsuit, most of his value was taken away by his wife and children.

No, he went back to his old job, entered the music department of a university as a teacher, and was actually rated as an associate professor after a few years.

Relying on the title of associate professor, he entered the Folk Music Association, and sat in the position of president step by step, and his title was also regularized, and he was also a powerful figure.

Cao Wu was a little puzzled, he was already a figure with food and drink, head and face, why should he covet the invention of a musical instrument? Is it necessary to take such a risk?

However, what he didn't know was that Guan Zhijun had basically come to an end when he got to the point where he was now, but the dream he had been haunting and never forgetting was to join the Music Association.

The Chinese Musicians Association is a national and professional musician organization, and if he can enter the Music Association, then he will really have no worries about food and clothing in his life.

However, perhaps it was his experience of going to the sea halfway that caused him to have not been able to join the music association until now.

Seeing that he is about to retire, if he doesn't work hard, he won't have a chance in this life.

"I must not let him be so rampant! I want to call the police!" Liu Wanxiang got up angrily, he felt annoyed at the thought of being tricked for more than two months, and losing people in front of relatives, friends and Cao Wu, and he wanted to beat up Guan Zhijun.

Cao Wu said: "Of course, the police have to be reported, but we have to discuss how to deal with his rebuttal, and we have to come up with evidence." ”

"Of course I have evidence! When I went to submit the materials, they were all under surveillance, and when I went to the patent office, I would be clear when I checked the video!"

"Generally, the storage time of surveillance video will not exceed one month, even if it is a government unit, it will not exceed three months, do you calculate, from the time you submit the materials to now, is there any three months?"

Liu Wanxiang thought about it, and his face turned a little pale: "It's almost ......"

Cao Wu nodded and said, "That's it, the video should have been overwritten, or he found a way to dispose of it, otherwise he wouldn't dare to make such a high-profile appearance." ”

"Then what can I do?" Liu Wanxiang panicked.

"Don't worry, I'll figure it out. ”

……

Liu Jingshu sent Cao Wu out.

Walking to the door, Liu Jingshu bit her lip, and suddenly said: "Cao Wu, don't worry, our family will be responsible for this matter, and we will compensate you for your losses, even if my grandfather can't afford to pay for it, I will compensate you." ”

"What stupid are you talking about?" Cao Wu said in surprise

Liu Jingshu lowered her head and said nothing.

Seeing this, Cao Wu stepped forward, put his hands on her shoulders, and said seriously: "Who said that you want to pay for it? Don't think about it, I will find a way to solve this matter." ”

Liu Jingshu's eyes were red, she had always shown herself in the style of a tomboy, as if she was not afraid of heaven and earth, but at this moment she knew her vulnerability.

She hated herself for not being able to help Cao Wu solve the problem, and a sense of frustration made her show a rare hint of a daughter who I saw pity.

Cao Wu's heart fluttered for no reason, and the ghost envoy reached out and pinched her face, and said with a smile: "Don't worry! When did I say nonsense? No one can snatch my things." ”

"Oh......" Liu Jingshu was a little flustered, and staggered her eyes urged: "Then you should go quickly! Otherwise, it will be too late to go home, and Auntie should be worried." ”

Cao Wu looked at her bright eyes under her broken bangs, and for some reason, he was a little reluctant to leave.

Liu Jingshu waited for a while, her mood calmed down a lot, and when she saw that he didn't move, she smiled and said, "Or, do you want to squeeze in with me all night?"

"Haha! next time!" Cao Wu smiled, turned around and walked out: "Let's go!

Zhang Rong had been sent to Xiangcheng by Niu Li, who had learned of the situation, and Cao Wu drove home in his car.

In the car, Cao Wu rubbed his temples and closed his eyes in thought.

That Guan Zhijun is a smart man and thoughtful, and when his side found out about the problem, he had already fallen into his pit.

How to break the situation at the moment is a difficult problem!

But he never lost confidence, as he said to Liu Jingshu, if you want to take my things, let's see if you have the ability first!

The next night, Zhang Jiaqian took Cao Wu to Grandma Li's house.

But the purpose of their trip was not to visit Grandma Li, but Uncle Meng.

After listening to Cao Wu's explanation, Grandma Li was also indignant, and immediately made a phone call.

Within ten minutes, there was a knock on Grandma Li's door.
