B录音室的声音

At ten in the evening, Xiao Zhou is the only person left at the campus radio station.

He organizes the program list while listening to tomorrow’s music.

Suddenly, someone is singing softly in Studio B.

Xiao Zhou walks over while asking, “Who is in there?”

After he opens the door, nobody is inside.

But the voice is still singing, even more clearly than before.

He checks the microphones while messaging the club president.

The president replies, “Did you turn on the graduation program from three years ago?”

Only then does Xiao Zhou discover that the old speaker in Studio B has been playing a senior student’s vocal test.

The next day, he changes the program title to “The Empty Room That Sings.”
