"Horseshoe" originally refers to the horny skin of a horse. In order to delay the wear of horseshoes, humans often nail a layer of U-shaped metal (often iron) on them for protection, so it is also called "horseshoe". In western culture, giving horseshoes represents love (only women can give them). It is an iron hoof tied to the hooves of horses, cows and other animals. Protection principle: Horseshoe consists of two layers. The first layer in contact with the ground is a hard stratum corneum about 2-3 cm thick, and the upper layer is a living stratum corneum. Horseshoe comes into contact with the ground, and will fall off quickly due to the friction of the ground and the corrosion of accumulated water. The main purpose of nailing horseshoes is to delay the wear of horseshoes. The use of horseshoe not only protects horseshoe, but also makes horseshoe hold the ground more firmly, which is beneficial to riding and driving.

Basic introduction Chinese name: Horseshoe originally refers to the horny skin of horses, alias: Horseshoe function: delaying the wear and tear of horseshoes, related stories, horseshoes, brief introduction M horseshoes According to historical records, horseshoes were first invented by ancient Romans around the first century BC, and were not widely used in the Central Plains until the Yuan Dynasty. Horseshoe, it sounds hard and cold-blooded, but in ancient Rome there was a very casual and romantic name called "horse sandals". The appearance of horse sandals is very playful. Although it is made of iron, it is quite light in weight and its edge contour is wavy. They were placed on horseshoes, and the horse came over with a very elegant expression. From a distance, the sound of "click" is very rhythmic. If you often take horses in and out of cobblestones or rugged mountains, in order to prevent horses from slipping, several "horse sandals" must have sharp nails, so that horseshoes can hold the ground tightly. Recalling the horseshoe I saw in the countryside when I was a child is really like putting a pair of sandals on a horse. It's just that the style is a little clumsy compared with when it was first invented. Because horses are increasingly used in production and military, there is no way to make a pair of high-quality shoes for horses. Due to the full development of iron smelting technology, horse sandals have become strong and durable. China's records about horseshoes are about five dynasties. In the third year of Tianfu at the end of Jin Dynasty (AD 938), Zhangwu was sent to Khotan and began to enter the vast Gobi from Ganzhou (now Zhangye, Gansu). Looking ahead, the road is full of sand and gravel, which is very difficult to walk. At this time, Ganzhou people taught them a technique, "It is feasible to teach the golden messenger to make a horseshoe with four orifices, and the horseshoe is also engraved with four orifices, and the camel's hoof is wrapped in yak skin." "Wood astringency" was a general term for horseshoes by northern nationalities at that time. It can be seen that Ganzhou Uighur in Hexi Corridor at that time had mastered the technology of nailing horses.

Before the war, the groom prepared horseshoe nails for the king. The blacksmith is busy hammering nails into Wang Jun's horse these days, and all the iron pieces are used up. Ask for it. The groom impatiently urged, "Your Majesty should take the lead and can't wait!" The blacksmith must cut an iron bar into four parts and then process it into a horseshoe. When nailing the third horseshoe, the blacksmith found that there were not enough nails. Ask for a nail. The groom said, "God, I heard the bugle call. I can't wait. " The blacksmith said, "Without nails, it is unstable." "Let it be, or the king will blame me." As a result, a nail was missing from the fourth paw of the king's war horse. At the beginning of the battle, the king led the army to the front. In the battle, an unexpected misfortune happened. His horse suddenly lost a horseshoe, and the king fell to the ground, and the frightened horse ran away. The king's misfortune demoralized the soldiers, who turned around and ran away. The count's army surrounded the king. In despair, the king waved his sword and sighed, "Oh, my God, my country was destroyed on this horse!" " "After the war, there was a folk song: a nail was missing and a horseshoe was lost. I lost a horseshoe and a horse. Lose a horse, lose a king. Lost a king, lost a battle. Losing a battle ruined a dynasty. Horseshoe horseshoe. Zhou Libo's "The Storm" Part I 18: "Lao Suntou said to Da Li! You're working while the iron is hot. Why do you have to cheat?

Regardless of men and women, they all know a little craft ... No way, they repair shoes, match locks and nail horseshoes. " Also known as "horseshoe".
