Mercedes slogan Guan Yu

The load of red hare. As we all know, the magic of red rabbit as a peerless horse lies in its extremely fast speed rather than super heavy. In order to give full play to the advantages of Red Rabbit, Guan Yu must not be allowed to use heavy weapons under the condition of constant weight. This common sense is as obvious as a full truck can't run at the speed of Mercedes-Benz.

According to the historical records, the dragon crescent moon blade weighs "82 Jin". According to the weight system of the Han dynasty, a catty is about 260 grams, and this knife is about 42 kilograms. Considering that Luo Guanzhong was a native of the late Yuan Dynasty and the early Ming Dynasty, it is possible to use the Yuan and Ming Metrology System, that is, one kilogram is about 600 grams, so the weight of this knife will suddenly rise to 98 kilograms, no matter which one is light.

Guan Yu's height is "nine feet long", which is about 2 1.35-23.75cm, which is about 2 meters according to one foot in Han Dynasty. At the same time, Guan Yu was a big man. According to the body mass index coefficient, his reasonable weight should be 180+, so the total weight of knife and man will reach 220-280 kg!

2. It is difficult to use the reins. To take a step back, even if this knife is real, there is nothing wrong with the record of "82 Jin", and the red hare is just an ancient magical calorie that can run out of the speed of Mercedes-Benz, so Guan Yu still can't play the role of the dragon crescent moon blade well. The answer is obvious because Guan Yu has only one pair of hands.

As we all know, Qinglong crescent moon blade is a long machete. If you want to play smoothly, you must use the strength of two hands to finish it. At this time, you need a third hand to help Guan Yu steer. Of course, this situation is absolutely impossible. It is precisely because of the limitation of using weapons on horseback that ancient warriors on horseback like to use bows and arrows and one-handed short-handled knives in battle, because the work of manipulating horses in archery can be completed in a short time by holding the horse's abdomen with both legs, while one-handed short-handled knives can free up one hand to control horses. This was the inevitable choice of the knights at that time, and I think Guan Yu was no exception.

At that time, stirrups had not been invented. Of course, some people will argue. Although there was no third hand to hold the reins, Guan finished the work with the stirrup. The stirrup is equivalent to the third hand of the knight, and its function can make the knight firmly tied to the horse, thus achieving the unity of man and horse. But unfortunately, there was no stirrup during the Three Kingdoms period!

As a country with a long riding civilization, it is a very strange phenomenon that China invented the stirrup very late. When was the stirrup invented? When we observe the terracotta warriors and horses of Qin Shihuang and the warriors and horses of Han Dynasty, we can't find any evidence of the existence of stirrups, but it was not until the late Western Jin Dynasty to the early Eastern Jin Dynasty that the prototype of stirrups was discovered, that is to say, stirrups were first invented during this period.
