Introduction to Nine Immortals Heavenly Gate: Xiangong Mountain is steep, with only one stone gate in the west and one in the north accessible. The north gate is called the "Xiaoai Gate", and the west gate is the main gate, which is the "Xianmen Gate". In 1998, the scenic spot was re-planned, the Immortal Gate was moved down under the old Tudi Temple, and another archway-style mountain gate was built, which was called the "Nine Immortals Gate".
