Stone Roller On The Sunning Ground Editorial Photo

Stone roller is one of the oldest agricultural tools in China and has a history of thousands of years. The harvested millet was spread on the ground or on a stone table, and the millet was repeatedly crushed by a man or a domestic animal with a stone roller until the shell of the millet was broken. Now, with the popularity of mechanical tools, these traditional agricultural tools have become museum exhibition supplies. This is the stone roller in the Museum of the pit Museum in Sanmenxia, Henan.
