The wall was high in temperature, so the condensate was formed on the wall, which caused the wall to be damp. Facing the wall, this situation generally only occurs in the winter, and it will be good in the summer, but the aftereffect is that it will leave a lot of unsightly mildew and affect the appearance of the wall.
