The slogan of the ancient army was "one, two, three". Later, one of their officers was from the south, and they couldn't tell the difference between "three" and "three". Therefore, whenever he shouts three in training, the soldiers always think that he is shouting "three" (abbreviation for dissolution), and he is dissolved after the exam. Moreover, during training, some soldiers walked well in front of the first two, but only when they heard this slogan, they were at a loss and always confused. Later, the leader thought that it would not last long, so he discussed changing it to 12 1. And it rhymes, echoes back and forth, and it sounds good to shout. Soldiers will never be lazy again. There are loopholes to drill. 12 1 is also a left and right hint, which facilitates training and improves training efficiency! Multiple goals, and even continue to this day!

And the origin of 12344: In the past, the number was 12345. Later, their chief was Lickitung, who always could not distinguish between "five" and "me". Then, when the number was 5, the soldiers fell into chaos. He always thought that the instructor was calling "me", so he stopped moving and waited for him to give other orders until the whole queue could not be normal. Then it is suggested that 1234 is only about, and 12345 is about. The next password, 12345 is about the same. In this cycle, most people often don't know which leg to take because of this slogan, so there are also many straight men who always step on one's foot and walk in line will be chaotic. Due to these disadvantages of the slogan 12345, a clever leader accidentally discovered that 1234 is an invisible symbol around, and the following 1234 is an infinite cycle around. So he had a brainwave and told the soldiers about this law. This law really played a great role, which not only overcame the drawback of mistaking "five" for "me", but also shouted 1234 with a high momentum and was easy to remember. The most important slogan is marching and standing. So it is universal!
