Introduction to Feiyunkou: Feiyunkou is located in the northwest of Qingyun Peak. It is a gap in the main ridge of Baishi Mountain. It is the main wind outlet and is connected to Lieping Valley. Because Baishi Mountain is tall and blocks the air circulation from the north to the south, Feiyunkou has become the main channel for wind and cloud to fly across Baishi Mountain and is the main place for "wind and cloud meeting".
