As one of the four ancient civilizations in the world, China has a long history and civilization. China's 5,000-year history, like the Yellow River and the Yangtze River, has been rolling in from the source. Today, we unconsciously entered the modern world. Looking back suddenly, the splendid civilization of the Chinese nation makes every Chinese descendant feel proud. The beautiful Yao and Shun gave way to saints, and the magical Dayu managed water and ushered in the dawn of Chinese civilization. The prosperity of Xia, Shang and Zhou Dynasties and the brilliance of Qin, Han and Tang Dynasties left a distinct impression in the history of Chinese civilization. The history of the motherland is glorious, and countless omnipotent people with lofty ideals have emerged. They shed their heads and blood, and are indomitable for the reunification of the motherland, the prosperity of the country and the prosperity of the nation. The great poet Qu Yuan cares about the country and the people. Wen Tianxiang, the anti-Yuan general, left a heroic oath with patriotic enthusiasm: "Since ancient times, no one has died unexpectedly, so we should keep an open mind and shine on history." . These heroes undoubtedly prove to the world that the descendants of the Chinese people are worthy of being descendants of the dragon!

Our motherland is vast, beautiful and rich, with a long history, splendid culture and brilliant science and technology. The Chinese nation is smart, enthusiastic, hardworking, creative, firm, resolute, brave and revolutionary. As descendants of the Chinese people, we are extremely proud and love our motherland.

Four great inventions:

The four great inventions refer to the four great inventions in ancient China that had great influence on the world. Namely papermaking, compass, gunpowder and movable type printing. This statement was first put forward by Joseph Needham, a British sinologist, and was later inherited by many historians in China. It is generally believed that these four great inventions greatly promoted the development of politics, economy and culture in ancient China. These inventions spread to the west through various channels and had a great influence on the history of world civilization.
