Were the ancient inscriptions written on stones by calligraphers?

There are two ways for the ancients to carve tablets: one is to write Dan, that is, to dip a brush in cinnabar (cinnabar: bright in color, easy to cut, granular, not turbulent and not deformed). The second is the later "copying stone", that is, writing it on paper first and then copying it on the tablet.

Song Sushi's "Thank you for seeing a poem": "Zhu wax is imitation, exquisite minutes." The method of carving was recorded.

Write the inscription on paper, cover the back of the manuscript with translucent paper (pay attention to the back, because you want to engrave the reverse word), and dip the pen in cinnabar (cinnabar is a red inorganic pigment with bright color and good moth-proof effect) to double-tick the handwriting. Then put the double-hook copy paper on the stone tablet, superimpose the multi-layer paper on the copy paper, and polish the stone evenly so that the double-hook silver ink sticks to the surface of the stone tablet. Then carve according to the traces of silver ink.
