"Advice from the geese" means that the geese fly south, and the ranks are orderly. The geese soar in the sky and sing from time to time, as if reminding and caring for each other. These reminders are the friendship and care of the geese, and also the embodiment of the spirit of unity and cooperation of the geese. In the process of migration, geese need to deal with all kinds of difficulties and challenges, and this warm reminder is a tacit understanding and cooperation between geese.
