Introduction to Migratory Bird Paradise: Every year after the 15th day of the eighth lunar month, migratory birds begin to fly to Lashihai. These "guest birds that fly thousands of miles away" are not at all reserved. They chirp and flap their wings, breaking the previous tranquility of the lake. From October to the Spring Festival, there are the most birds. Birds come here in flocks from their hometown in the far north. Together with the local birds, they play freely in lakes, swamps, mountains, forests, and meadows, fishing and shrimping, creating a peaceful scene. "Swallows come and go on the beams, gulls love each other in the water." The beautiful scene described in the poem truly exists here. Throughout the winter, they were happily swimming around, recuperating, and replenishing their physical strength to prepare for their return home in strong health in the coming year.
