The specific procedures are as follows:
The first is to read the manuscript, that is, to carefully check the sample manuscript written by the calligrapher: size, line spacing, structure, arrangement and so on. Then choose the right stone, first rough grinding with sand, then grinding with sand skin, and then grinding with fine knife brick until it is greasy and slippery. Then brush the stone with thick fine ink, which is called "inking". When the ink is dry, flatten the white wax with a soldering iron, so that the ink is evenly covered with a layer, and then cut off the thick excess with a spatula. In addition, the original inscription should be covered with transparent paper, and the "double hook" with fine brush and ink line should be used, and then the "double hook" with silver red as the red line is called "crossing Zhu". On the waxed stone tablet, properly spread transparent paper "crossed with ink", pad wool felt with a wooden pestle, and tap the word "hook" to make the red line of "double hook" clearly printed on the wax surface, and then engrave.
As for the inscription of Yin and Yang, I think the landlord knows it. Explain "double hook": a technique commonly used in meticulous painting to shape. Xu Lanting's famous "Copying the Dragon" has been passed down to this day through double-hook copying.
The landlord should give points appropriately.
