There are two main methods. One is that calligraphers use Zhu Mo to engrave directly on stones, and then stonemasons carve them. The other is the mole, which uses the double hook method to copy the original calligraphy on the stone and then carve it with a knife. This method is often used in the works of famous calligraphers. So in the past, stone carvers often had a lot of contact with famous calligraphers. Many stone tablets are engraved with not only the names of calligraphers, but also the names of stone carvers. Unfortunately, this traditional business may soon disappear or have disappeared.
