"September 18" is a history that the Chinese people cannot forget。Ninety-two years ago today, Japanese imperialism deliberately stirred up trouble and invaded northeast China, creating the "September 18 Incident" that shocked the whole world。Due to the non-resistance policy of the nationalist government, within 6 hours, the Northeast Army's North Battalion fell, within 8 hours, the entire city of Shenyang fell to the enemy, and in more than 4 months, the northeast of 1.28 million square kilometers was occupied。The "September 18 Incident" in 1931 became the starting point of the Chinese people's War of Resistance against Japanese Aggression, and opened the prelude to the World Anti-Fascist War。

This is a national history of pain and humiliation, a national history of never giving up and constantly struggling, and a history of the Chinese nation's struggle for world peace。The Communist Party of China became the mainstay of the war of Resistance against Japan, and the anti-Japanese national United Front united with the broadest forces to persevere in the war of resistance, and finally won the first complete victory in the anti-aggression war in nearly a century, and re-established China's status as a major country in the world。US President Roosevelt once said: "China's resistance is an important factor in the final victory over Japan."。This great victory opened up bright prospects for the great rejuvenation of the Chinese nation and started a new journey for the ancient China to rise from the ashes。

The past is clear, the future is safe。Only those who have experienced the transition from war to peace know the preciousness of life.Only a nation that has experienced from crisis to rejuvenation can understand the strength of the family and the country as one, and understand the significance and value of national rejuvenation and national prosperity。When young people prosper, a country prospers, and when young people are strong, a country is strong. If the young generation has ideals, ability and responsibility, the country has a future and the nation has hope。
