Swallows mouth is in Tailuge National Park~ The environment is very beautiful~ The plant cover area is oversized~~~ It feels like a green lung! ! ! The rainy weather does not affect the mood of the tour at all~ The water is not shocked, walking through the stone cave, and there are cars driving slowly from time to time. It seems to be one of the models of harmonious coexistence between people and nature~~~~ Wear a helmet here, blue, great!
