Introduction to the Mother and Child Stone: One of the nine strange stones in Chaya Mountain. The two groups of rocks have been weathered and eroded to form a landscape of mother and child monkey pictographs. Together with the world's best stone monkeys, they form the Chaya Mountain Stone Monkey Courtyard Landscape Group. This pair of mother and child stones is caused by granite undergoing spherical weathering under the control of joints. Later, the weathering cracks became wider and wider until the surrounding rock blocks became unstable and collapsed, leaving the upright single stones to continue to be weathered and denuded. The gentle joints of the original layer weathered into fissures, and the fissures continued to be weathered and denuded and gradually widened, causing one side of the rock block to be suspended and unstable. Small stone monkeys were formed by sliding along the vertical joints, and the more stable rock blocks were large stone monkeys. The combination of the two When raised up, it looks like a mother and child depending on each other, so it is called the mother-child stone.
