Heated bronze pressed to bone: each crack was the ancestors' answer, read only by the king.

Royal scribes incised pictographs with a graver so precise the strokes survive three thousand winters.

Vermillion pigment rubbed into each cut made the characters legible; the bones were then buried in temple pits.

What began as a king's private oracle grew into the root system of the longest-living writing tradition.
