Introduction to Songtou Wu Waterfall: Songshutou is located at the southern end of Saihu Lake. It is a low pass in Keguqin Mountain and is an important gateway from Bozhou to Yili via Guozigong Pass. The middle and high mountainous areas in the Yili Guozigou area on the south side of Saihu Lake are often covered in clouds and fog, and the dense forests of Keguqin Mountain on the south side of Hunan are also surrounded by fog and waterfalls. When visitors come here, they feel as if they are in the sea of ​​clouds in Mount Huangshan, and all of them are excited.
