Introduction to Shili Gallery: Shili Gallery, also known as Huangluowan Cliffs, is known as "Three Hunan and One Wonder". The cliffs are towering and majestic, extending from north to south along the west bank of the Mekong River, with a length of 3,500 meters. The cliff section is almost upright, like a huge barrier of the Great Wall. Due to weathering, the cliffs form colorful and strange pictures. The colors change with the seasons, morning and dusk, forming a colorful Ten Mile Gallery, which is unique in China. .
