1. is beneficial to the drying of animal fur. When slaughtering animals, experienced people will directly peel off the whole skin of the animals. There used to be sheepskin, mink and so on. Usually used to make coats, especially warm in winter, while dog skin, rabbit skin, weasel skin and so on. Can also be used as gloves, etc. , are particularly warm. There used to be many hunters in the countryside, and people would come to the village to buy the furs of these animals. Rabbit skin used to be very valuable. You can't do it if you peel it. It must be dried slowly in the shade, otherwise it will rot. In the past, the earth walls were all plastered with lime, so the fur on the walls can be cured, which is helpful to dry in the shade and not easy to rot.

2. Conducive to fur formation. People who have seen animal fur stuck to the wall in the countryside must know very well that the fur nailed to the wall is very flat and has several legs from beginning to end. The purpose of nailing fur to the wall is to prevent the skin from wrinkling. This is because the main component of animal skin is collagen, which is easy to curl together if it is not smooth. Even if it's dried in the shade, it's useless, so nail it flat on the wall to avoid fur deformation. Of course, there is another reason to nail the skin on the wall, which is to play a decorative role, just like putting up a wall painting now. But mainly because of the first two aspects.

3. Conducive to anticorrosion. Drying the fresh skin until the water content is 12% ~ 16%, which creates unfavorable environmental conditions for the growth and reproduction of bacteria and achieves the purpose of preservation. The specific method is: first shake the fur of the hide, with the fur facing down and the fur facing up, spread the limbs according to the natural shape, spread them on the board or stick them on the wall, and be careful not to stretch them too much until the leather board is removed after it is set, and then put the leather board facing up and dry it in a cool and ventilated place. In the process of drying, it is necessary to prevent sun exposure, antifreeze and human and animal trampling.

3. Conducive to plastic surgery and hair trimming. In order to make the planed leather board smooth, it needs shaping. Nail the hair face down on the board and dry it in the shade to avoid sun exposure. After drying in the shade, smooth your face with pumice or sandpaper, then remove the trimming on the nail plate and comb your hair with a comb. If the skin is broken, it has to be sewn, and then it's all over.
