Will Kunming enterprises come to Wuhan for recruitment?

Some, but not many. You can submit your resume yourself. If the company thinks you can, it will arrange an interview at the nearest recruitment place, not necessarily in Kunming. I'll give you a few good machinery units: Kunming Large Road Maintenance Machinery Factory, Hongyun Honghe Group, Kunchuan, 705 Research Institute, 750 Research Institute, Kunming Machine Tool Factory, Yunnei Electric Power, Yunnan Tobacco Machinery Factory, Yunnan CY Group, Huaneng Lancang River and so on. I hope I can help you.
