What is the three-line construction of 40 fire "one set of three factories"? What does "one set" mean?
On this issue @ Lupin 2017 friends, should have asked me three times.
40 fire "a set of three factories" is a special period of words, specifically refers to:
The third plant is the production of Type 69 40 mm rocket launchers, namely: anti-tank rocket launcher factory, anti-tank rocket factory, rocket fuze factory.
At the end of 1969, after the defense of Zhenbao Island in the last century, in order to prevent the "steel torrent" of the northern powers, the state decided to build three "40 fire" production supporting plants for the production of anti-tanks in Xinjiang, Gansu and Jilin (3 factories in each place, a total of 9).
Regarding the "set", I had wondered whether the "40 fire" bazooka was commonly known as the "set", but I did not find any relevant evidence.
Therefore, from what I have learned so far, the "one set" of "one set of three factories" is "building supporting factories together";
