Talk about the meaning of the poem The Great Wall is indestructible, so why be afraid of caterpillars shaking the dragon?

Celebrating the 70th anniversary of the victory of the Anti-Japanese War,

Military parade in front of Tiananmen Square.

The three armies marched across the sea,

The iron army rushed across the sea.

The long arrows look up to the sky proudly,

The war eagles weave rainbows in the sky.

The Great Wall is indestructible,

Why fear that a caterpillar might shake a giant dragon.

The Great Wall is indestructible, so why are we afraid of tiny caterpillars coming to shake the giant dragon? The Great Wall is the symbol of China, the caterpillar refers to foreign enemies, and the dragon refers to the powerful motherland. Praising the prosperity and strength of the country, the bravery and might of the army, and the thoughts and feelings that are fearless of foreign enemies
