画后面的声音

Before closing, Xiao Lin hears a soft sound behind an old painting.

She does not dare move it, so she has her coworker go call the curator first.

The curator has them turn off the exhibition hall music and listen carefully again.

The sound is like a small bell, coming out from the wall one beat at a time.

Xiao Lin remembers a thin line hidden on an old map.

That line makes her think there may not be a wall behind the painting, but a small door.

The curator has security take down the painting, and an old mechanism is indeed revealed behind it.

Decades ago, it would make a wooden bird fly out of a box to mark the time.

The next day, a repair technician gets the wooden bird moving again.

Xiao Lin says this sound makes the tiny museum seem as if it has woken up.
