Introduction to Heifengkou: Heifengkou is located in the valley where Hutou Peak and Qisan Mountain are connected. It has cliffs on both sides and deep valleys. It has the potential of "one man can guard the pass, and ten thousand people cannot open it". The wind here is strong and urgent, and there is a saying that "there is no wind and the waves are three feet high, and the wind blows the head away", so it is called "Heifengkou" and is known as the most dangerous pass in Liangshan Mountain. There is now a statue of Li Kui and the Black Wind Pavilion, as well as a hand-written monument by the famous calligrapher Sha Menghai.
