Introduction to Ruilian Holding the Sun: Dengjiao Mountain overlooking the sunrise in the east is a wonderful sight in Shanhaiguan. This is the scenic spot known as "Ruilian Holding the Sun". Ruilian holds the sun on the top of Jiaoshan Mountain and overlooks the sunrise in the east. It is a wonderful sight in Shanhaiguan. It is recorded in the annals: "It is about to dawn on the top of Jiaoshan Mountain. Looking down, you can see the sunrise in the sea, surrounded by red clouds, like a rosette. When the sun rises, the seat sinks into the pass." There is a poem from Kaitai in the Qing Dynasty: "The sky thousands of miles away is brilliant in the clouds, and the clouds contain the dawn, and strange flowers appear. Thousands of petals of Taiye fly in, and flowers ten feet high pour out of the red basin." This is a praise for this scene.
