Wu Yunjiu (ぶぅんちょぅきゅぅぅ)
([Currently] the earliest information is found = =")
In the samurai era, a "\" will be held for boys over five years old.
Let's take it apart first to see the literal meaning:
Wu Yun wins and loses his fate. また, samurai? Soldiers are doomed.
(The fate of winning or losing in a battle. Or as a samurai? The fate of a soldier)
Long-term growth. Forever. (for a long time. Forever. )
Long-lasting martial arts とは
"から Long-lasting martial arts" (のでののぐのぐぐぐぐぐぐぐぐぐぐ )
(I hope to lift the draft and pray for long-term military luck) Pray for the soldiers on the battlefield to be lucky forever. (This is the significance of the transformation to World War II)

On the national flag of Japan, (called "Rimaru Flag" and "Rizhangqi")
The signatures in it are all the signatures of parents, family members, relatives, friends, colleagues, neighbors, etc. of soldiers, and written words of blessing.
(This flag of Wuyun Changjiu can be used as historical materials, and there are quite a few such things in Japanese yahoo auctions = mouth =)
In addition, the word "Thousand Needles", which has the same meaning as Wuyun Changjiu and Wuyun Changlong, is also a prayer for soldiers to win and seek peace on the battlefield.
