There is some distance from the old city of Duyun. Although there are buses to get there, the shifts are relatively scattered, and it is convenient to take a taxi. The museum directly uses the old site of the Oriental Machine Tool Factory during the third-line construction period, so the appearance is very old. The exhibition inside is not monotonous, adding a lot of sand plate models and physical equipment, the content introduced is also very professional. Since there are really not many museums that tell the third-line construction in China, I think it is worth seeing. I don't know if it is still in the epidemic prevention and control stage. There are very few visitors and the surrounding area is very depressed. I really can't help it with such a good tourist resource.
