1969年3月至8月间,中苏边境接连爆发了几起冲突事件,之后,大军压境的苏联于下半年又私下向美国等国试探对中国核设施发动突然袭击的可能性。在此背景下,我国开展了防范“新沙皇”侵华战争的紧张战备和疏散在京中央领导人的工作。由于事件发生在“文革”期间,当时林彪、江青反革命集团风头正健,在他们的一手操纵下,被“疏散”人员实际上是换了个地方继续被“监禁”。 From March to August 1969, several conflicts broke out on the border between China and the Soviet Union. After that, the heavily stricken Soviet Union tentatively explored into the United States and other countries the possibility of launching a surprise attack on China’s nuclear facilities in the second half of the year. Against this background, our country has carried out intense war preparations against the “tsarist” invasion of China and evacuated the leaders of the Central Government in Beijing. As the incident took place during the “Cultural Revolution”, when Lin Biao and Jiang Qing counterrevolutionary cliques were in full swing, their “evacuees” actually changed places and continued to be “imprisoned” under their single-handed manipulation.
