Introduction to the Martyrs' Tombs: The Martyrs' Tombs are located on the fourth floor and are the main part of the cemetery. The heroic souls of 361 martyrs (including 120 unknown ones) are laid here. Most of them are the remains of martyrs who sacrificed their lives to liberate the coastal islands of Yuhuan, Pishan, Jishan, Yangyu, Dalu and Xiaolu. The tombs are divided into three floors, with two rows on each floor, arranged in an arc along the mountain. There is a tomb passage in front of each floor, and a bluestone tablet is engraved on each tomb with the names of the martyrs. Among them, the young hero Lin Senhuo was buried alone in a flat altar in front of the tomb, covering an area of ​​about 410 square meters.
