After the Millennium Festival, the night is cool and the day is hot.

After the Millennium Festival, the night is cold and the day is hot: after the Millennium Festival, it will still be hot during the day and cool at night.

White dew festival and climate change: The white dew solar term falls in early autumn, which usually corresponds to mid-September in China. At this time, the temperature began to drop gradually, and you can still feel the warm sunshine during the day, but it has become cool at night. At this time, the meteorological conditions gradually transition from summer to autumn, and the atmospheric humidity gradually decreases, so it is warm and sunny during the day and cool at night.

The meaning of "it is cold after the Millennium Festival and hot during the day": This proverb reflects the typical characteristics of autumn weather, that is, the climate change after the Millennium Festival.

It specifically expresses the meaning of the following aspects:

The night temperature drops obviously: after the Millennium Festival, the night temperature will drop obviously and become relatively cold. People may need to add more clothes to keep warm.

The temperature is higher during the day: although it is cold at night, it is sunny and the temperature is higher during the day. People can enjoy the comfort of warm sunshine in autumn.

Large temperature difference: "cold nights and hot days" means that the temperature changes greatly after the Millennium. This climate change may have an impact on people's health and dress choices.

Remind people to pay attention to the temperature change: this proverb also plays a role in reminding people to pay attention to the different characteristics of autumn weather, especially the large temperature difference between morning and evening, so it is necessary to make warm preparations and adjust clothes in time.

Generally speaking, "it's cool after the White Dew Festival and hot during the day" is a vivid folk saying, which is used to describe the characteristics of autumn weather and emphasize the change of temperature and the climate phenomenon that people need to pay attention to at this time. This also reflects the sensitivity and attention of ancient farming culture in China to solar terms and natural phenomena.
