Where did you go after the smog cleared?

Haze = fog+haze

Fog:

When the relative humidity reaches 100%, the water vapor in the air will condense into fine water droplets suspended in the air, which will reduce the visibility on the ground. This weather phenomenon is called fog. Fog is more common in spring from February to April. When the visibility in the atmosphere is lower than 1 km due to the condensation of suspended water vapor, meteorology calls this weather phenomenon fog. Conditions for fog formation: cooling, humidifying and increasing water vapor content.

Haze:

Also known as haze and haze, it refers to the turbidity phenomenon of unknown reasons caused by the suspension of a large number of particles such as smoke and dust. The core substance of smog is dust particles suspended in the air, which are called aerosol particles in meteorology. In recent years, with the increasingly frequent "smog" weather phenomenon, air quality has gradually deteriorated. Haze contains hundreds of atmospheric chemical particles, which intrude into human respiratory tract and lung lobes unsuspecting, thus causing respiratory diseases, cardiovascular diseases, blood system, reproductive system and other diseases, such as pharyngitis, emphysema, asthma, rhinitis, bronchitis and other inflammation. Long-term exposure to this environment will also induce lung cancer, myocardial ischemia and injury. Smog also often causes traffic accidents.

Conditions for fog formation: cooling, humidifying and increasing water vapor content. So after the weather clears up, most of it will disperse.

The core substance of smog is dust particles suspended in the air, which are called aerosol particles in meteorology. So the weather is fine, and it is estimated that it will have little impact.

To sum up, after the weather cleared up, the fog dispersed and the haze remained, but it was visible to the naked eye and became invisible.

Actually, when you stay in a dark room and come in through a small hole, you can see floating dust.
