What's the job of hitting stones?

Masons! Masons are a hard job, and they often say: strike while the iron is hot, and one day is two days. In the early years, almost every household needed them. Shi Gandang, mortar, tablet, inscription, stone mill, table, stone lion, etc. were all carved by masons.

Masons often use two hammers, steel drills, hammers and chisels. Masons quarried in the mountains during the day, and when they came home from work at night, they had to forge iron tools to quarry, which was very tiring and bitter. In the past, anyone who wanted to be a stone picker had to learn from the master. He must choose a toolbox for free every day for a year, and then he can do it himself after several years.

Stones can resist erosion, but masons can't resist the danger of falling off a cliff and being hurt by stones.
