In 1903, the Japanese Mitsurui Otani entered the hinterland of China in the name of religious investigation to carry out intelligence work in geographical exploration, when passing through Changsha, China, the branch of the expedition led by him, under the leadership of the Japanese businessman Hatoyama Yoshishi, stayed in a mountain town one hundred and sixty kilometers north of Changsha City for nearly three months, and when he left, the expedition team was only six people, and a week later, Hatoyama Yoshishi submitted a 16-page report to the Japanese Nissin Trade Research Institute to the Ministry of Foreign Affairs, known as the Hatoyama Report. The report mentions "things" buried beneath this mountain town.

On August 4, 1949, Cheng Qian, director of the Kuomintang Changsha Pacification Office and chairman of the Hunan Provincial Government, and Chen Mingren, commander of the First Corps, rebelled in Changsha, and Changsha, Hunan Province was peacefully liberated. The next day, the Fourth Field Army entered Changsha, and that night, as the person in charge of the Changsha Department of the Central Special Branch, I urgently summoned an old man and talked for three hours.

This old man's name is Gu Qingfeng, since he was 23 years old, he is the watchman of the old Changsha Railway Station, and I asked him about an incredible thing that happened at the Changsha Railway Station more than 10 years ago. From the old man's account, I gradually saw the beginning of the strange incident that spread widely and was amazing.
