Introduction to Langyin Pavilion: Langyin Pavilion is located at the top of Langyin Mountain in Junshan Mountain. It is said to be the place where Lu Dongbin recited poems. Legend has it that every time Lu Dongbin traveled through Yueyang and came to Junshan to recite poems, someone built a two-story pavilion where he drank wine and chanted, and then fell asleep drunk and slept soundly. He named it "The Place where Lang Yin flew over", also known as Lang Yin Pavilion.
