Mainly enterprises that do online monitoring.
They have done a good job in online monitoring in Hunan.
However, the online monitoring industry is shrinking at present, but their company must have handled the relationship with the local environmental protection department, so it should be transformed into an environmental protection project in the future.
Remember, if it is not a production enterprise, as long as it has a good relationship with the environmental protection department, it will definitely have a future.
But it's hard to say how much money you have, but I also believe that as long as you have the ability, the boss will definitely value it.
Good luck.
