Little Li heard a "thump thump thump" running sound from the ceiling on the first day he moved into his new apartment. He reassured himself: it might be a child playing.

But the noise continued from morning till night—moving furniture at six in the morning, skipping rope at noon, and high heels on the floor late at night. Little Li, with dark circles under his eyes, went to knock on the door, but it was an innocent-looking old lady who opened it: "I live on the first floor, there’s no one above you."

The property management checked the registration form: Little Li lived on the top floor, and there was no one above him!

The strange events escalated. He heard the sound of marbles falling while showering, and a woman humming a lullaby while trying to sleep. One time, the rice cooker even cooked undercooked rice by itself. Until one day, when Little Li found faded wallpaper behind the wardrobe, revealing a newspaper headline from 1978: "Single woman gives birth in apartment, baby’s cries lead to neighborhood complaints..."

That night, when a deafening cry came from the ceiling, Little Li suddenly laughed. He raised his electric drill and aimed it at the load-bearing wall—since reasoning didn’t work, let the one upstairs hear what noise really is.
