How do you know I can't? (Please add to your favorites)

"Damn, Su Yunqin really understands."
"I knew something felt off, turns out a lot was cut out."
"And the drum sounds okay at first, but if you listen closely, it's very different from the original."
"Exactly, Su Yunqin's comments are spot-on. In the song 'Mountains, Waters, Wind, Moon,' the instrument used isn't really a drum, it's actually a 'fou.'"

Inside the live broadcast studio.
While the camera captured the subtle expressions on Tan Linfang and her group's faces, many netizens versed in music also began to speak up.
The difficulty of the song 'Mountains, Waters, Wind, Moon' lies in the fact that many of its musical techniques are textbook-level.
There have even been academic papers analyzing the complexity and number of skills used in it.
So, for ten years, few have attempted to perform the full version; most renditions are heavily abridged.
The various arrangements are decent, but the original version is just too hard to reproduce.
Tan Linfang's version was already close, but Su Yunqin still managed to pick out many shortcomings.

On stage.
Tan Linfang's dissatisfaction became more obvious by the minute.
At the judges' table, Su Yunqin continued indifferently, "Moreover, there's another crucial point you all missed in 'Mountains, Waters, Wind, Moon.'
The drum on your stage isn't the one required for the song; the original used a 'fou,' and the segment with fou playing and singing is the most important part of the second half.
After the fou, there's a segment with chimes, which should be played together with the bianzhong bells as the grand climax of the whole performance.
Yet you abandoned it entirely.
If you were adapting the song for a purpose, that would be acceptable. But you brought out what you're best at and discarded the essence of the song.
I truly don't understand—after such a modification, you still want to challenge Professor Shao? Where does your confidence come from?"

"The chimes are a lost instrument!"
Tan Linfang couldn't take it anymore; she sneered from the stage, "Do you even understand chimes? Can you play them? I bet you can't. If you don't, how can you expect others to?"

"Damn, why is Tan Linfang so annoying?"
"This is the first time the Iron Lady girl group feels unlikable."
"Right? She doesn't even understand herself, and when Su Yunqin points it out, she refuses to admit it."

Before Su Yunqin could respond, the audience in the studio and the viewers online were already expressing their distaste for Tan Linfang's remarks.
Previously, everyone knew that Tan Linfang's group had a reputation for being prickly.
But since they had skill, people didn't mind.
Now, though, their lackluster performance and refusal to admit fault, even questioning Su Yunqin in return, had soured public opinion.

Granted, Su Yunqin might not know, but shouldn't she at least show humility?
For a moment, many quietly sided with Su Yunqin.
At that moment, a loud thump was heard on the set—Liang Feiyue, who had previously kept her green light on, switched it to red.
Picking up the microphone, Liang Feiyue said, "Tan Linfang, I passed you earlier.
But now, let me explain why I don't want to pass you anymore.
Your attitude is deeply displeasing to me.
Professor Shao Xinghui's reputation in the music world is undeniable.
Though Professor Su may not have his achievements, I know a bit of music myself. If she can point out flaws, you should reflect, not retort.
With an attitude like yours, I dislike it, and I don't believe advancing will benefit you."

"Heh, heh heh,"
Seeing Su Yunqin remain silent while Liang Feiyue spoke up and boldly turned off her green light, Tan Linfang laughed coldly.
"You're just an actress, what would you know?"
Bang!
Another green light went off, replaced by red.
This time, Wang Tao changed his decision.
"Your words are too aggressive. Like the other judges, I am eliminating your group!"
Wang Tao announced.
Whoosh—
The atmosphere froze.
Tan Linfang's expression visibly stiffened as she stood on stage, clenching her teeth.
At that moment, Luo Zizhen spoke up, "Don't you think you're being too harsh? Advancement and elimination are decisions that require careful consideration.
But you're treating them so lightly.
And frankly, I don't think Tan Linfang's group did anything wrong.
Professor Su, do you even know how to play chimes?
Many instruments in 'Mountains, Waters, Wind, Moon' are already lost to history.
When adapting, should we keep insisting on using lost instruments? Of course not. It's about playing to our strengths. If they're lost, we shouldn't force it.
Unless you can play them yourself, demanding others to do so is unreasonable!"
...

"Why do I feel Luo Zizhen makes sense?"
"Yeah, his words do have a point."
"True, Su Yunqin's demands are a bit..."
The audience and netizens who had just been annoyed by Tan Linfang now began to agree with Luo Zizhen.
The noise resumed, and all eyes fell on Su Yunqin.
Under the camera, Su Yunqin smiled softly; when Luo Zizhen's words targeted her, her smile suddenly blossomed.
In that moment, she truly smiled from the heart.
"Professor Luo, how do you know I can't?"
She replied calmly, with a smile.
That single sentence sent shockwaves through the studio and the live broadcast.

"Damn, did I hear that right?"
"I thought I was hallucinating—did Su Yunqin just say, how do you know she can't?"
"No way, Su Yunqin can play the chimes?"
In 'Mountains, Waters, Wind, Moon,' the use of fou was already astonishing.
After all, in five thousand years of Chinese musical tradition, before Western notation, music was only expressed through the pentatonic scale.
Even the guqin was recorded by finger notation, not staff notation.
This meant that over five thousand years, much of the musical heritage was lost.
The ability to use fou in a song already showed how extensive the musical knowledge of "Big Fire" was in those days.
But the chimes remain a mystery to most people even now.
Because, to this day, no one believes that an internet singer could use chimes as an instrument in their music.
And not only use them, but use them so well—by the second half, the song transports listeners back in time, as if watching ancient musicians perform.
Sadly, aside from "Big Fire"'s original recording, no one has managed to reproduce it perfectly in over ten years.
So, Luo Zizhen's words seemed reasonable.
Expecting others to master what you yourself can't is unfair.
But now, Su Yunqin claimed—how do you know she can't play chimes?
