On the evening of July 7, 1937, the Japanese side falsely claimed that a Japanese military drill soldier was missing and requested to enter Wanping County east of Lugou Bridge for search. This unreasonable request was firmly rejected by the Chinese garrison. The Japanese army used this excuse to mobilize heavy troops and bombarded Wanping County brazenly. At the same time, they launched an attack on the Chinese defenders of Lugou Bridge. Twenty-nine officers and soldiers of the Chinese garrison could not bear it anymore and fought back. That day, it was raining heavily, the Yongding River was surging, and the anti-Japanese officers and soldiers were highly motivated. The fierce fighting continued until late at night on the 8th. The Chinese army that came for reinforcements and the Wanping garrison cooperated with each other to fight fiercely with the Japanese army at Lugou Bridge and annihilated all the invading enemy troops. This was the Lugou Bridge Incident. The Lugou Bridge Incident fired the first shot of the entire nation's anti-Japanese war.

On August 13, 1937, the Japanese army launched a large-scale attack on Shanghai, and the Chinese army rose up to resist. The Nationalist Government mobilized more than 400,000 troops to participate in the war and fought fiercely for three months, dealing a heavy blow to the Japanese aggressors.

Later, under the leadership of the Communist Party of China, the Chinese people fought hard for eight years and won many battles. In August 1945, Japanese imperialism was finally defeated and the great victory of the Anti-Japanese War was achieved. At that time, the soldiers had only one sentence in their hearts: "Japanese imperialism! Long live the Communist Party of China!"

Our current life is all earned by the anti-Japanese warriors with their lives and blood and sweat. We must also learn from them, the "Japan" in our hearts - difficulties, and learn the courage of the soldiers to defy difficulties.
