How to clean and maintain walnut? A method to identify the authenticity of hand playing walnut

Walnut is not only a very nutritious food, but also a good way to keep fit. So how can we use walnut to keep fit? Some elderly people even play with walnut in their hands, so how can we keep it?

What's the advantage of playing walnuts by hand

1. Exercise the flexibility of the hand. At the same time, there are many acupoints on the hand, corresponding to different parts and organs of the body. You can often play walnut with your hand and massage the acupoints, which is beneficial to the body and stimulate the acupoints on the palm.

2. Playing walnuts by hand can exercise hand muscles and brain flexibility. It is not easy to degrade hand function. Crocus, brisk, abductor pollicis muscle, insensitive, hand three yin through, hand and brain complement each other. There are three yang on the hand, scattered in order. When two walnuts rotate in their hands, the walking is complicated.

3. When rubbing walnuts, the function of blood vessels can get benign training and flexible action in an inadvertent time. In traditional Chinese medicine, connecting the thumb artery is the best way to exercise the palms and fingers, and the meridians and organs are connected. The ulnar and radial arteries extend their branches on the way down. They should participate in palmar muscles and joints. They can massage and delay conduction. They can also watch almost all hand bones, such as collections and moonbones.

How to maintain walnut

1. Before new walnuts are used, they must clean up all the dirt in their tendons before playing. Otherwise, they will not be able to brush after being coated. A pair of good walnuts will be destroyed. The new walnuts should be brushed with a small amount of water with a bristle brush (white ones rather than black ones), especially for the first time, they must be brushed at least half an hour because they can't be brushed with water later.

2. After brushing, wipe it with toilet paper, wrap it up and put it in a plastic bag to dry in the shade. At least 10 days later, you can play with it. This process can't let the walnut see the wind and light, or it may crack. Until a few months later, walnuts began to be coated, and they would not crack.

3. Later in the process of playing, you must brush frequently to avoid trouble. Otherwise, the color of walnut is ugly chocolate color. You should clean your hands before playing. You are not allowed to play walnut.

4. It's better not to grease or rub the oil on the walnut's face. First, it's disgusting. Second, it's not good for the walnut itself, because the walnut itself will turn oil. When you paste it with oil, the skin color will be very ugly and brown.

5. Use toothpick brush to clean walnuts.

How to distinguish the true and the false of playing walnut by hand

1. Texture: if the real walnut is new, it has a strong sense of wood. If you look at the skin of the walnut, it will have a similar wood texture (not the concave convex texture of the walnut itself), while the pink walnut does not have that kind of wood texture.

2. Feel: real walnuts, even new ones, feel smooth when kneaded (except for catalpa and lantern, but these two varieties are relatively cheap, and there are few fake ones), while pink walnuts feel special.

3. Weight: if it's a new walnut, it's relatively heavy. The old walnut should be relatively light, because the water evaporates. If you weigh it in your hand, it feels like two big stones, it's basically resin

4. Color: old walnuts are not always red, some of them are not red, but the real color of old walnuts must be in-depth and natural, which makes you feel that it is the same color from inside to outside, like a carved jade, which can see the inside of the transparent luster; fake walnuts and dyed walnuts feel that the color is not thorough and transparent.

5. Luster: the old walnut has a thick coating. The luster is elegant dark light, similar to the feeling of mahogany furniture. The luster of the fake walnut is dazzling, and it feels like plastic, resin and glass.

6. Common sense: the most important common sense is that there are no two leaves in the world. There are also no two perfect walnuts. If you find that their lines and sizes are exactly the same (or extremely similar), and their shapes are particularly perfect and correct, you should be careful. It's very unlikely that you, a scholar, will find such a large price. To put it bluntly is to put the mentality in order, not to be greedy for perfection, not to expect to pick up leakage.
