Which comes faster, maple leaf red or white dew?

The Millennium is a solar term in the lunar calendar, and the time is around September 8 in the solar calendar. It means that the weather is getting colder and colder, and the dew on the grass is getting thicker and thicker. You can see the dew in the morning, so it is called the white dew.

Maple leaves won't turn red until they arrive in beginning of winter at the end of the first frost (the time is 1 1.08). At this time, frost comes to the earth, and deciduous trees wither their leaves in the cold wind to keep out the cold.

But now that the earth is warming, the defoliation time may be delayed.
