As time goes by, time flies. After more than 70 years of changes, many cities have become neither humanized nor materialistic. Who were the top 20 cities in China more than 70 years ago? 1937 Six metropolises with a population of over one million before the outbreak of the Anti-Japanese War: 1.77 million 2. Beiping1.53 million. Wuhan 1.35 million 4. Guangzhou1.2005. Tianjin11.36 million. Nanjing. Great changes have taken place in China's population and industrial layout. The industrial center of gravity has shifted from the east with Shanghai as the center to the west with Chongqing as the center. Western cities such as Chongqing, Chengdu, Xi and Kunming have developed and their populations have increased rapidly. Chongqing increased from 470,000 in 37 years to 1.25 million in 45 years, Chengdu from 5 1.00 in 37 years to 740,000 in 47 years, and Xi from 654,337 years. Affected by the war, the population of many cities once fell sharply, especially Nanjing, Wuhan, Guangzhou, Hangzhou and Changsha. Due to the atrocities committed by the Japanese invaders, the population of Nanjing decreased from 1, 0 1 000 in June 37 to 1 700,000 in February 38, and recovered year by year. After 45 years, it recovered about 700,000, and reached the peak value of 1.33 million at the end of 48 years. Affected by the Battle of Wuhan, Wuhan City was severely damaged in the war. The population dropped from 1.35 million in 35 years to 450,000 in 39 years and recovered to 1.25 million in 42 years. After being bombed by the US military, the population dropped sharply again, leaving only 790,000 in 45 years, and then it recovered year by year, but it never exceeded that before the Anti-Japanese War. Due to the Japanese bombing, the population of Guangzhou dropped from 654.38+0.2 million in 37 years to 540,000 in 39 years, and then recovered year by year, reaching a peak of 654.38+0.42 million in 48 years. Hangzhou dropped from 590,000 in 37 years to 6.5438+0.8 million in 38 years, and then rose year by year, but it never exceeded that before the Anti-Japanese War. During the eight-year Anti-Japanese War, the Japanese invaders invaded Changsha many times, and the time affected by the war was the longest, from 540,000 in 37 years to 240,000 in 45 years, with only over 400,000 on the eve of liberation. Cities in the northeast are special, and the situation is different because they settled in early. Before the September 18th Incident, Shenyang was 6 1 10,000, Harbin was 400,000, Dalian was 300,000, and Changchun was10.2 million. During the occupation, a large number of Japanese expatriates, Koreans, foreign businessmen and customs officers flooded into the Northeast, which led to the rapid growth of urban population in the Northeast. After Japan surrendered, a large number of Japanese and foreign nationals were sent back to China. Coupled with the influence of the civil war, the population of cities in Northeast China showed a downward trend. In 45 years, Shenyang has increased from 3 1, 6 1, 000 to 654,380+0,880,000. During the civil war, it once fell to more than 900,000, and then it quickly rebounded. According to the first census 1953, Shenyang has a population of 2.3 million, ranking fourth after Shanghai, Beijing and Tianjin, so Shenyang is also an underestimated city. Changchun became the capital of Manchukuo during the occupation, and its population increased rapidly, from1.2000 in 32 years to 890000 in 44 years. After Japan surrendered, there were only over 500,000 left, which once fell to 1.8 million during the civil war. Dalian increased from about 300,000 before the fall to more than 800,000 in 45 years, and fell to more than 500,000 during the civil war. Harbin increased from 400,000 in 32 years to 690,000 in 45 years. Harbin was liberated earlier and was unaffected by the civil war, reaching 720,000 in 47 years.
