First of all, I want to say that China's manufacturing industry is not developed. I studied mechanical manufacturing, let me talk about some of my experiences.
When I worked with the masters in the factory day and night to improve the accuracy of the CNC machine tools by one level, translating German materials, when I went through great hardships without holidays or overtime pay, covered in dirt, with wounds on my hands, failed many times in operation but finally succeeded in processing and manufacturing samples that met the expected accuracy of 0.0001 millimeters, I was excited for a while, but soon felt a sense of loss because the CNC machine tool for that machining center was made in Germany, the numerical control computer part was made in Germany, the processing software was also made in Germany, even a lathe tool, a drill bit, were made in Japan! Except for the factory building, none of the tools were made in China! Even the factory building was based on foreign experience.
