“大三线”这个名词,对中老年人来说并不陌生。但大三线究竟是什么样的。可能还鲜为人知。早在60年代中期,三线建设问题就已经提出并付诸实施了。当时我们对国际形势的分析是:战争不可避免,要立足于大打、早打、打核战争。因此,我们的基础工业,特别是国防工业要往西南腹地转移,西南腹地山区就叫做大三线。毛泽东主席对加速大三线建设有过许多指示。他说:三线建设搞不好,我睡不着觉。建设三线,没有路,骑毛驴去;经费不足,拿我的稿费去……。为了响应毛主席号召。多少工人、技术人员、干部离开了条件优越的老厂和舒适繁华的大都市,拖家带口来到一无所有的穷山沟。他们披荆斩棘,奋力拚搏,排除万难,前赴后继。为大三线建设付出了青春,付出了一生,有的甚至付出了生命。他们与天斗,与地斗,克服了各种难以想象的困难.创造出一个又一个奇迹。本文作者吕慧敏,毕业于清华大学。1970年底,她离开了劳动一年多的航空工业部机关五七干校,被分配到航空工业在大三线的一个基地——汉中航空工业基地工作。在那里。她一呆就是10年,目睹和亲历了三线建设的艰难困苦,挫折失败,拚力斗争和取得的成果。在犹有战乱的今天,在加速开发西部贫困地区的时候,回首大三线建设的往事,也许会让人们感悟到点什么。 “Big Three ” is the term, is no stranger to the elderly. But what is the big three line? May be little known. As early as the mid-1960s, the issue of the third-line construction has been put forward and put into effect. At that time, we analyzed the international situation as follows: The war is inevitable. We must base ourselves on cracking down, early fighting and nuclear war. Therefore, our basic industries, especially the defense industry, must be transferred to the hinterland of the southwest. The mountainous area in the hinterland of the southwest is called the third line. Chairman Mao Zedong has many instructions to speed up the construction of the three major lines. He said: The construction of the third line is not good, I can not sleep. Construction of three lines, there is no road, riding a donkey to go; lack of funds, take my royalties to ... ... In response to Chairman Mao’s call. How many workers, technicians and cadres left the old factory with comfortable conditions and comfortable and prosperous metropolis, and dragged their families to the poor ravines with nothing at all. They cling to the clutches, struggling hard, to eliminate all difficulties, go on going. For the construction of the third line paid youth, paid a lifetime, and some even paid their lives. They struggle against heaven and fight against earth, overcoming all sorts of unimaginable difficulties and creating miracles one after another. The writer Lu Huimin, graduated from Tsinghua University. At the end of 1970, she left the Labor Department of the Ministry of Aviation Industry, which had worked for more than one year, to be a cadre of cadres. It was assigned to the aviation industry base in Hanzhong, a base of the aviation industry in the Third Route. over there. She stayed for 10 years and witnessed and experienced the hardships and difficulties of the third line construction, the setbacks, the struggle and the achievements made. In a time when war is still running out and accelerating the development of poverty-stricken areas in the west, it may remind people of what they were doing when they look back on the major and third-line construction.
