Introduction to Jiutuling Pass: The mountain ridge at the junction of Kangmen Scenic Area and Deqing County is called Jiudongling. It was an important pass from northern Zhejiang to Hangzhou in ancient times. According to legend, the patriotic general Yue Fei of the Southern Song Dynasty fought nine fierce battles with the Jin soldiers here, so it is also called Jiutuling. Half of the ancient city wall is now in ruins.
