First of all, you must have a pioneering spirit in doing business, and you can't just rely on any relationship. But it is not absolute. It's easier to deal with things in the real world. To do fire fighting, first of all, I think you should know fire fighting. I don't know why you do this job, whether you listen to others or think for yourself. I think there is a reason. There is a lot of fire fighting knowledge, and the fire fighting business is also divided into engineering and equipment sales. I don't know what you want to do. If you only sell equipment, it's very simple. Just rent a store and contact the business. Of course, it would be better if there were firefighters. If you are doing engineering, you need a lot of first money, and you have to apply for qualifications. It is very difficult to do it, and it has never been done before. In any case, business needs to know the market. According to your own strength, you can do it with your heart.

I wonder if my answer is useful to you? I sincerely wish you success!
