Yan Guan, half a kilometer downstream of the lawn, looks like an ancient purple and gold crown, hence the name Yan Guan. Ganhuan spring flows out of the rock all the year round, so it is also called Ganyan. It is also called Yan Guang because there is a glimmer of light at the top in the dark cave. In 26 years, Li Zongren wrote the word "Yan Guang" at the mouth of the cave. Yan Guan has a winding path leading to a secluded place. The cave weighs four or five times, and water flows through it, with beautiful scenery, warm in winter and cool in summer. It is also connected with Anji Rock, where water can flow in and out of the land. It has the depth of Seven-Star Rock and the grandeur of reed flute cave, which is the highest among all rocks. Yan Guan has been officially opened to the outside world since 1995. Here, the mountains are beautiful, the water is clear and the caves are beautiful. In addition to the wonderful crown rock, there are three-star cloud villas for rest and accommodation. As night falls, you will attend the national song and dance party in Yunshan Villa, and warm folk songs will bring you into the ocean of joy. Everyone will dance hand in hand around the burning bonfire. At this time, the mountain breeze is cool and warm, which makes people forget all the troubles and tiredness of the day and enjoy the peace of mind and a precious friendship.
