Will it get cold when the geese fly north?

During the cold dew period, the lowest temperature in northern China has reached below 0℃, and the first frost began to appear. Sometimes, affected by the strong cold air from the south, the temperature in the south of China plummeted, resulting in "cold dew wind" weather. The geese began to fly south from the white dew to the cold dew, so they flew north to warm the weather.

Every autumn and winter, geese flock from their hometown Siberia to the south of China for the winter. The following spring, after a long journey, they returned to Siberia to lay eggs and breed. The flying speed of geese is very fast, which can fly 68 ~ 90 kilometers per hour, and the long distance of thousands of kilometers is only one or two months.
