I want to know the answer to the following question:
What are some major cities occupied by the Chinese during the Second Sino-Japanese War?
All the background I'm provided with is that "In the 20th century, as Beijing, Shanghai, Nanjing, and Wuhan had all been occupied by the Japanese during the Second Sino-Japanese War, the capital of the Republic of China had been temporary relocated to Chongqing, then a major city in Sichuan.". Is that enough to answer the question?
