There are many theories about the origin of salute, but most of them show that the origin of salute is Europe. There are several more credible ones: one is that the soldiers of the ancient Roman legion raised their hands above their heads when they saw officers, similar to the posture of blocking the sun. This is to show respect for superiors, who are as bright as sunshine. Compared with the salute posture in European countries now, it is indeed very similar to the sunshade posture. There is also a saying that the salute posture originated from the knight period in Europe. According to legend, in the Middle Ages, many knights were active on the European continent. These knights belong to different camps. At that time, knights usually wore heavy armor helmets, and when they met, they would raise their goggles to show their identity, similar to the wind protection of motorcycle helmets now. Over time, they formed a habit. Even though the chivalry has passed for a long time, European soldiers will make similar gestures to show their friendship when they meet. I wonder when they will meet under the official unification.
During the period when European colonists came to all continents to carry out colonial activities, salute gestures spread all over the world, especially in North America. The colonists here developed this salute into? Hatting ceremony? This has also become the most formal etiquette in America. From film and television works, we often see people often take off their hats at funerals to show their memory. The salute of China army experienced a long development, and the salute posture began to be standardized during the Kuomintang period. During the War of Resistance against Japanese Aggression period, due to the scattered distribution of the army of the * * * production party, it was difficult to unify the types of firearms, and the simplest salute was used in military ceremonies. After the founding of New China, the salute posture was further standardized and became what it is now.
