Chen Ke came to the hanging clock, whose dark wooden body had already begun to fade and whose plastic dial cover had yellowed. His grandfather had bought it when he was still in his prime, almost half a century ago.
The pendulum swung methodically, but the second hand refused to move. Curious, Chen Ke moved a stool next to it and climbed up, eager to study it closely.
After feeling around the side of the clock, Chen Ke opened the cover and held the pendulum, stopping its motion. Beneath the pendulum box, he found a winding key.
This type of old wall clock needed winding intermittently, or else it would slow down, making the time inaccurate.
Chen Ke inserted the key into the hole in the dial, mimicking how his father used to wind the clock, and he turned it vigorously a few times. In an instant, the sky outside released a ringing ding-ding-ding-ding of a bell.
