those girls didn't know what really happened back then. if they knew, they would have embraced the Japs and have great fun with them. they were actually allies.
The proof of this is that Japan announced defeat on 15 August 1945, but it was 1 October 1949 that the PRC was founded. During this four-year period, the KMT and the CPC waged a fierce civil war. Accordingly, the PRC’s claim that the PRC is a state created by defeating the invading Japanese army is factually incorrect. Also, the myth that CPC forces fought valiantly with the Japanese army during the Sino-Japanese War is untrue.
On the contrary, during the Sino-Japanese War, Mao Zedong concentrated his efforts on conspiring with the Japanese army to weaken the KMT forces. He planted communist spies such as Pan Hannian in the Japanese Foreign Ministry’s local agency Maison Iwai and sold KMT military intelligence obtained from the National Government in Chongqing through the KMT-CPC Cooperation to the Japanese at a high price, creating an environment in which it was easy for the Japanese military to deal blows to the KMT forces.
And that is not all.
Mao Zedong sent Communist spies to make direct contact with the Japanese army, even going as far as to propose a truce between the CPC forces and the Japanese army.
This paper compares and contrasts Japanese sources, such as
Memories of Shanghai, the memoir of Iwai Eiichi, and Chinese sources to examine questions such as “what did Mao Zedong do during the Sino-Japanese War?” and “how did the CPC forces grow stronger?”
