Our dear motherland has suffered a lot in the modern history of 100 years. Do you know this humiliating history? If so, can it be targeted at

From 1840 to 1949, China experienced the Opium War and the baptism of artillery fire in the past 100 years. Whether it's humiliating the country in the Opium War or War of Resistance against Japanese Aggression's final victory, the cruel lesson tells us that if we fall behind, we will be beaten. And based on the forest of nations in the world, we must be at the forefront of the world.

Examples: Opium War, Second Opium War, Sino-Japanese War of 1894-1895. Eight-Nation Alliance's war of aggression against China. (expansion: content, meaning)

Summary: The above examples fully reflect the lesson that backwardness will lead to beatings, and tell us not to forget the national humiliation and revitalize China.

I hope it helps you.
