Poetry about the destruction of the country

This poem means that after the 9 18 incident, the whole three northeastern provinces fell under the Japanese aggressors. Japan annexed Northeast China, and 30 million compatriots became conquered people. Soon, the Japanese invaders extended their claws to North China and East China, and finally launched the Lugouqiao Incident on July 7, 1937, and began a full-scale war of aggression against China. More than half of China fell into enemy hands, and Japanese invaders occupied our country, killed our people, plundered my property and resources, which brought profound disasters to our people. We can never forget this humiliating history!
