What do you mean by waving a fan before the Japanese charge?

During the Warring States Period, Japanese military commanders held a fan with the official name "Pei Jun".

Military distribution is military distribution. Holding military equipment means pointing out the military configuration, that is, directing operations.

Zheng Ruo, the aide of Hu Zongxian, the governor of the Anti-Japanese War, once recorded: "The Japanese are used to a butterfly array. When they get cold feet, they wave their fans and everyone dances with knives."

Military equipment looks like a round fan with ears on the handle. It is usually made of leather, wood or thin iron and coated with paint or gold and silver powder.

During the Japanese Warring States Period, the most famous story about military distribution was the "one-on-one fight" between Takeda Shingen and Uesugi Kenshin, known as the two heroes of the Warring States Period.

At that time, Shangshan Jianxin, wearing a yellow armor and a white scarf, rode a famous horse into this array in Takeda Shingen, and cut at his old enemy Xinxuan with a three-foot knife, but Xinxuan was blocked by the army.

The earliest military equipment appeared in the middle and late period of Kamakura shogunate, which was equivalent to the early years of Ming Dynasty. The military commanders Ota Daoguan and Kitajima Zaoyun both recorded military competitions. During the Warring States period, military competitions gradually became popular. At first, it was a divination tool for "military matchmakers" to calculate yin and yang, judge good or bad luck and predict astronomy. The army usually paints twelve heavenly stems and earthly branches, the moon, stars, Yin and Yang gossip, twenty-eight stars and even Sanskrit, all kinds of mysteries.

During the melee of the Warring States period, apart from the name, only senior generals at the division level were eligible to join the army.
