There is a bath downstairs in my house, and the chimney of the bath boiler room is only as high as the first floor. Every day, there is so much soot near my balcony that I can't even open the window?

You can call the environmental protection hotline or the fire hotline. Because his emissions exceed the standard and are unqualified, this kind of thing should belong to the environmental protection department, so if you call the environmental hotline, and his chimney is only as high as the first floor, it may cause a fire, so if you call the fire hotline, they will also sort it out. They will certainly take care of this bathtub. They must be rectified and meet the standards before they can be allowed to operate.
