What does migratory bird group mean?

Travel routes. Migratory Bird Groups Just like the migration of migratory birds, middle-aged and elderly people from the north come to the warm Huizhou coast to spend the winter to avoid the cold winter tourist routes. The reason why "migratory bird tours" emerged in the travel agency business is very simple. At that time, the majority of tourists wanted to go to the warm south and spend the winter without having to worry about food, accommodation, and transportation. The destinations selected by travel agencies for them were relatively inexpensive. The price-performance ratio is very high, and it is a cost-saving and friendly place for tourists and tour groups.
