When will it frost?

The weather became colder and colder when the first frost appeared. It is called the first frost, and the time is usually on June 23rd 10. The first frost this year was also on June 23rd, 10. At this time, the sun reached the longitude of 2 10 degrees, and the weather was colder than before, so cold that dew could condense into frost. The first frost in autumn is called "first frost" and "first frost", and the last frost in spring is called "late frost" and "final frost". During the period from early frost to late frost, it is essential to keep warm.

But because of the different latitudes, not all places will be frosted. At this time, frost has appeared in the Yellow River basin, but in places with lower latitudes, such as the southern region, there are still three solar terms welcoming the first frost. Therefore, the first frost reflects the climate characteristics of the Yellow River Basin. Even at the same latitude as the Yellow River, the first frost may not always appear due to the different geographical heights.
