Does it get cold when geese fly north?

Wrong.

During the cold dew period, the lowest temperature in northern my country has reached below 0℃, and the first frost has begun to appear. In the southern region, sometimes due to the influence of strong cold air moving southward, the temperature drops suddenly and "cold dew wind" weather occurs. . Wild geese fly south from the white dew to the cold dew, so flying north means the weather gets warmer.

In autumn and winter, wild geese fly in large groups from their hometown in Siberia to the south of my country to spend the winter. The next spring, after a long journey, they return to Siberia to lay eggs and reproduce. Wild geese fly very fast, flying 68 to 90 kilometers per hour, and the long journey of thousands of kilometers takes a month or two.
