When will it clear up?

It will clear up at 9 am. Because it is usually sunny, the brightness of the sun after four o'clock in the afternoon should be between nine and ten in the morning, and the brightness of that sun should be similar during this time. Of course, I think there will be some differences in different places, such as different latitudes and the time of sunset and sunrise. I'm talking about it in Henan Province, where I live.
