My grandfather was a stone engraver, specializing in carving tombstones for dead people.
Before he died, he passed me a carving knife with one word engraved on the handle - "Guan".
I thought it was a mark of family craftsmanship until I carved a monument with it for the first time.
The stone tablet itself cracked a crack.
A hand reached out from the gap and grabbed my wrist.
In the palm of that hand, there is an eye.
