Introduction to the Shanmen Archway: The entrance to Nanshan is the traditional Shanmen Archway, with four pillars, three doors and five floors in the northern official style. The lower shelf is a white marble carved stone pillar and beam, and the upper shelf is a wooden tile structure. The main plaque in the Ming Dynasty is "Yanshan Yuxiu" in Kujin's double-hook running script, and on the back is "Luanshui Zhongling".
