Look at the back of the stone first, that is, the Shi Gen or the bottom: Is there any red and yellow mortar attached to the root of the stone, and it is hardened, not stuck? Second, look at the stone skin and stone lines: the stone skin in Shi Zhuan is bright and moist, smooth as congealed fat, and has excellent touch (the characteristics of thinness, wrinkles, permeability and leakage do not affect the stone skin). There is a special white-gray stone grain in the stone muscle, and the grain is naturally clear and smooth. The original groove is V-shaped, and the artificial stone pattern is U-shaped. If washed with water, artificial stone patterns will appear immediately, and the water will dry slowly, while the original stone patterns will dry quickly. Third, tap to listen to the sound: tap with your fingers or tap with a wooden stick, you can hear the sweet and crisp sound. The ancient Qing dynasty and the so-called "eight-tone stone" are the stone of the spirit.
