What are the large-scale machinery enterprises similar to Xugong and Sany Heavy Industry in Jiangsu? I am a junior in mechanical design and want to find an internship unit.

Generally, large heavy industrial enterprises will have branches or business departments there. Besides the two you mentioned, there are Zoomlion, Rong Sheng Heavy Industry and so on. However, the top three industries are Sany, Zhonglian and Xugong. The latter two are state-owned enterprises and Sany is private. However, the background of the machinery industry is not good at present. Many companies have stopped hiring, and some companies have laid off employees. State-owned enterprises may be relatively better.
