19 14 years, the first world war broke out, when China was under the rule of the northern warlords. Since 19 17, the war situation has become more and more clear, and countries have joined the war and joined the allied forces represented by Britain, France and Russia. China also sent troops to Europe. Although he was only an engineer, many people died in World War I, like a meat grinder. 19 18, the war ended in the surrender of the allied forces.
Soon, the Paris Peace Conference-a meeting to punish the defeated countries after the war-was held. As a victorious country, China sent representatives to attend the Paris Peace Conference. At that time, Shandong, China was occupied by Germany, and the representative of China demanded to recover Germany's rights and interests in Shandong. Germany is a defeated country. But British Prime Minister Lloyd George and French Prime Minister Clemenceau controlled the Paris Peace Conference, and they wanted to transfer Germany's rights and interests in Shandong to Japan. Although Gu Weijun delivered an impassioned speech at the peace conference, there is a famous saying: "China cannot live without eastern Shandong, just as the west cannot live without Jerusalem". The participants were very moved. The weak countries have no diplomacy, and China's reasonable demands are rejected.
The news of China's diplomatic failure at the Paris Peace Conference reached China, and soon the May 4th Movement broke out. Angry students held a demonstration and burned down the houses of three people, including the foreign minister of Beiyang government at that time. In this movement, the working class in China stepped onto the historical stage, and the May 4th Movement also became the beginning of China's new-democratic revolution.
