The main job of a fire trainer is to popularize fire knowledge, publicize fire emergency treatment and daily prevention knowledge, which is a life-saving industry, rather than selling fire-fighting equipment.

You should look at this work from the perspective of great security and people's livelihood, not just selling it. Otherwise, the effect is not good and the taste is not good.

Imagine that if your statement is in place, you can analyze and explain the problem in combination with the actual environment and situation of your audience, so that they can realize the practicality and the seriousness of the consequences and launch safer, simpler and more reliable fire-fighting equipment in time. Who else will refuse you? Successful fire instructors and after-school fire-fighting equipment are in short supply.
