Do you want to be a factory inspection consultant or an auditor of a factory inspection agency? As a consultant, if you can have customers, it will be a big way to "make money", and a factory inspection consultation fee will cost 20 thousand to 30 thousand! Do three or five a year and you can rest! Haha, of course it's not easy, but now foreign investors have to inspect the factory when placing orders. For people who have no experience in factory inspection, of course, they can't do the fraud you mentioned themselves, so you have relevant information as soon as you come, and you know how to do it. More and more factories need your orders!
To be honest, I also want to develop in this area! I have started to collect information in my blog. You can have a look and we can communicate in the future!
