The significance of studying China's modern history-
What's the use of studying the modern history of China? Of course, we should pay tribute to the Qian Qian compatriots who died innocently under the guns of foreign enemies, remember the desperate struggle of the people in Sanyuanli, remember the heroic sacrifice of 250 Zhiyuan soldiers, and remember the patriotic acts of the "Six Gentlemen of the 1898 Movement", "Seventy-two Martyrs in Huanghuagang" and countless revolutionary pioneers who gave their lives for justice. But the most important significance is to learn from this painful history, strive to improve ourselves, do a good job today, and write the future history of China.
The modern history of China began with the Opium War in 1840, which is of extraordinary significance. If China is still immersed in the dreamland of great powers, then China has been dragged into the world stage by the armored ships of great powers. There can be no isolated peace. Whether you like it or not, you have no choice but to be forced to fight. Since then, the world has experienced two world wars, and the struggles of oppression and anti-oppression, aggression and anti-aggression have emerged one after another. In a sense, this worldwide contest continues to this day; Although the political structure, power contrast and contest mode have changed greatly than before, it is obvious that any country or nation wants to be in a more active and favorable position in the competition for survival and development. Even today, when peace and development dominate the world trend, challenges and contests still run through it.
Today is an extension of the past and the starting point of the future. In order to grasp today and the future, we need to learn from the mirror of history and become a wise and intelligent nation. As far as the development of a country is concerned, there are reasons for prosperity and reasons for decline. Therefore, studying the modern history of China is of great help for us to grasp the opportunity, push forward the reform and realize the grand strategic goal of "three steps".
China's modern history is rich in content, but there are three lessons learned from suffering, which can be said to be the most unforgettable.
