The Opium War was the first imperialist invasion of China in modern times, and treaty of nanking was the first unequal treaty humiliating China. It has taught us many lessons, the most important of which are two points: first, we will be beaten if we fall behind; Second, weak countries have no diplomacy. The Opium War was also the beginning of China's modern democratic revolution. After the Opium War, China was opened and became a semi-colonial and semi-feudal society. The main social contradictions have changed, namely, the contradiction between imperialism and the Chinese nation, feudalism and the masses of the people. The main task of the revolution is to overthrow the cruel rule of imperialism and feudalism. The people of China rose from great shame and were determined to save the nation from peril. First, in 19 1 1 year, the Revolution of 1911 led by Dr. Sun Yat-sen overthrew the old corrupt Qing government, and then in 192 1 year, the China * * production party was established, leading the people of China to change from the old democratic revolution to the new democratic revolution. After 28 years of hard work, it finally reached 65438. President Mao Zedong wrote in the inscription of the monument "Immortality of People's Heroes":

In the past three years, the people's heroes who died in the People's Liberation War and the People's Revolution are immortal!

For more than 30 years, the people's heroes who died in the people's liberation war and the people's revolution are immortal!

This can be traced back to 1840. Since then, in order to oppose domestic and foreign enemies, strive for national independence and people's freedom and happiness, the people's heroes who died in previous struggles are immortal!

The inscription "1840" is the Opium War of 1840. This major historical event is not only a national humiliation, but also a wake-up call. No matter how long it takes, it will always be engraved in the hearts of China people!
