Walnuts are made of wood. By playing with walnuts, we can get the vitality of wood, so the yang in our body can get hair growth. In addition, when we play Wan Wen Walnut, we can adjust the six meridians of the palm through it. For example, when we are playing, we can massage the "Zhongchong" on the tip of the middle finger and the "Laogong" on the palm. Because these two acupoints are part of pericardium meridian, it is equivalent to doing pericardium meridian massage every time during massage, which is of great benefit to the center.
In the palm of our hand, besides the six classics, there are nine hexagrams (also called Jiugong). Their parting areas are dried melon, cantaloupe, root melon, real melon, easy melon, likua, kungua, single melon and medium melon. The changes of these nine hexagrams directly reflect the changes of the five internal organs of the human body. For example, the divination area is located in the thenar below the thumb, such as the size of the thumb head, which mainly reflects the core and waist and legs. Gengua belongs to the soil and governs the spleen and stomach. If the vein of the root melon area is exposed, and the palm print of "well" or "rice" is exposed, it will be clear that the human body is deficient in spleen and cannot be wet, which is easy to make the waist and knees weak. After the above symptoms appear, we can remove the palmprint on the palm by playing with hemp walnuts. The disappearance of palmprint also shows that the symptoms of spleen deficiency in human body have been alleviated. "Walnuts can live to ninety-nine, and never leave their hands", which is the true meaning of Wan Wen Walnuts.
I believe that after reading these explanations, you will know that Wan Wen Walnut has so many cultural connotations and understand the specific reasons why middle-aged and elderly people favor it. I suggest that you often play "Wan Wen Walnut" in your spare time, because in the process of playing, you can massage Wan Wen Walnut to several acupoints on your hand, which is very beneficial to your health.
