What is the whole poem about crossing a horse into Tokyo with a knife?

The whole poem is as follows:

There are a billion soldiers in the Great Wall of Wan Li.

National humiliation does not treat future generations.

Willing to mention 100 thousand tiger and wolf brigades,

Jump into Tokyo.

The author of this poem is unknown, and it is widely circulated on the Internet. During the Anti-Japanese War, Chiang Kai-shek once said that "an inch of rivers and mountains and a drop of blood, 100 thousand teenagers and 100 thousand soldiers", but this poem should be an anonymous generation, with hatred for the Japanese, imitating ancient poems.

In the first half of the 20th century, the most popular phrase in China was "400 million compatriots", which was a broad understanding of the population of China at that time. Before 1949, China never had a population of one billion, so there would not be one billion soldiers. So this poem should be exaggerated to express the author's indignation.

Poems describing War of Resistance against Japanese Aggression are:

1, Zhang Huanwu-Slaughterhouse

In the fierce battle, Qiu Cheng was fascinated by the sun, and the soldiers and civilians contributed to the country and became a torrent.

Strangers kill chickens and dogs, and only Western jackdaw in the west cries around trees.

2, Zhang Huanwu-"The Battle of Xiangcheng Solid"

The Eighth Route Army went down to Taihang Mountain, and the horseshoe in jathyapple was frosty and cold in spring.

When the sun sets, people cross swords, and ghosts of ancient roads jump from beams.

All sides of the army shook Beidou, and ten sides shot Sirius.

The first shot of the Japanese invaders, Xiangcheng Gu and Megatron Plain, was wiped out.

3. Zhangjiaji-Guerrilla warfare

In the green gauze tent, the guerrillas are heroic.

A diversion from east to west bombed the bunker, and the enemy's lair was hit hard from the inside.
