Which is better, Xi 'an Aeroengine Group Co., Ltd. or Xi 'an Aeroengine Factory?

Almost. Xi 'an Aerospace Engine Factory is a professional manufacturer that develops and produces large-scale liquid rocket engines under the Sixth Research Institute of China Aerospace Science and Technology Corporation. The leading product is the Long March series liquid rocket engines. As long as Xi 'an Aeroengine Factory produces turbojet engines, turbogenerators, turbofan engines, gas turbines, etc. , such as "Qinling". I have been to Xihang Airlines, and I feel that the factory building is rather shabby. The treatment is average. Let's go to space flight. After all, with the support of the institute, the benefits are better. In fact, the company led by AVIC is regarded as a hungry ghost.
