There is a smell of sweat in the room.

It will take three years to paint the new special room with lime and other things! Harmful gas is released! Mainly in summer, I know my body has been sweating! All kinds of flavors are mixed together! Think about what it is and ask! Your home needs ventilation now. It's too hot and too cold to stay indoors! In hot weather, the gas is constantly evaporating! People should not stay indoors for a long time. If it's cold, harmful gases will evaporate slowly, but you can't keep ventilation in the house! Sometimes I feel upset and nauseous.
