Huangshan often sees the sea of clouds after the rain.

Because of high humidity and water vapor. The most suitable time for Huangshan to see the sea of clouds is foggy weather. After all, you can't see anything in fog. After the rain clears, no fog is the best time to see the scenery.

Extension:

Generally speaking, there are many foggy days in Huangshan, with more than 200 days a year, and the weather forecast is often inaccurate. On the day of the rainstorm, the tour guide said that the weather forecast released before May Day in Huangshan was all rainstorm, but the weather was particularly good on May Day, so if you want to go on sunny days, if you look at the weather forecast, you'd better choose several consecutive sunny days. Don't be afraid of heavy rain, because it is likely to be a sea of clouds after rain, ok.
