I have been working as an equipment engineer for almost 4 years before, but suddenly I found that I no longer like this industry and wanted to change careers, but I didn't know what to do.

Equipment engineers are mainly technical personnel engaged in all aspects of equipment management, equipment management system construction, equipment technical guidance, or equipment bidding, bid evaluation (equipment procurement), equipment inspection, organization of equipment maintenance and direct sales of equipment manufacturers. You have worked for four years, and you must have some relevant skills. If you don't want to do this job now, you should ask him to think carefully about what he wants to do. What are the advantages? Then decide that it is best to have something to do with your previous work experience, so that it will develop faster.
