In the process of playing walnuts, people use the spikes, bumps and edges of walnuts to exercise their hands by rubbing, rubbing, pressing, pricking, pinching, rubbing and rolling, and press the acupoints on their palms to stimulate the reaction areas on their hands, so as to achieve the effects of relaxing veins and dredging collaterals, promoting blood circulation and removing blood stasis, and strengthening the body.
because the walnut skin is thick and firm, after long-term rubbing by hands, wetting by sweat, penetrating by oil and polishing by time, it finally becomes a natural art product with bright inside and transparent red inside, and agate is not better than agate. In the minds of people who play with walnuts, walnuts are not only fitness equipment, but also a work of art, but the apple of their eye that integrates playing, fitness and viewing.
