Did the geese fly this year?

Whenever autumn and winter come, geese will fly from the north to the south for the winter.

Every autumn and winter, the cold climate in the north is no longer suitable for geese to survive, and geese will fly to the warm south.

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. Maintain a strict and orderly formation during the flight, that is, form a "human" shape or a "one" shape. Wild geese fly back to the north to breed after the vernal equinox every year, and fly to the south for winter after the autumnal equinox.

The formations in the sky are either "one" or "people" when flying, and they are arranged in the order of generations from beginning to end, which is called "geese". The leader of the array is led by the old goose. It is also a manifestation of herd instinct that geese are arranged in neat herringbone or zigzag. Because it is conducive to defending against enemy damage.

The geese fly south to egrets, with 24 solar terms, starting from September 7 to 9 every year. "Cold dew geese fly south, chrysanthemums bloom". "In August, the geese open their doors and bring frost to their feet." The geese started from the white dew to the cold dew and flew south.

The home of these geese is in Siberia. Every autumn and winter, they migrate to the south in droves. There are two main ways to fly: one route starts from the northeast, passes through the Yellow River and the Yangtze River valley, reaches the coastal areas of Fujian and Guangdong, and even reaches the Nanyang Islands; The other way passes through Inner Mongolia and Qinghai, and reaches Sichuan and Yunnan, even as far away as Myanmar and India for the winter. The next year, he flew back to Siberia to lay eggs and reproduce.
