Due to the effect of the head geese flapping their wings and driving the airflow, if the geese fly in the shape of "human" or "one", the geese in the back will fly very easily and do not have to rest many times. In the process of flying, the head geese will form a low-pressure area behind them, and the geese that follow can make use of this low-pressure area to reduce air resistance, which is beneficial to the continuous flying ability of the whole group.
