1928年至1937年,郭沫若逃亡日本,在日生活9年。在日期间他一直受着日本警察的监视,失去言论及作品发表的自由。1934年郭沫若在《沫若自选集》序文中暗示了他所处环境的危险和艰难,他说:“我目前很抱歉,没有适当的环境来写我所想写的东西,而我所已经写出的东西也没有地方可以发表。在闸门严锁着的期间,溪流是停顿着的。” From 1928 to 1937, Guo Moruo fled to Japan and lived in Japan for nine years. He has been under the watch of the Japanese police during the day, losing his freedom of speech and publication. In his preface to the “Moro Selections,” in 1934, Guo Mo-ruo hinted at the dangers and hardships of his environment. He said: “I’m sorry, I do not have the proper environment to write what I want to write, and I have written There was no place to publish anything, and the stream was stopped during the lock-in period. ”"
