A 70-year-old man in Suining, Jiangsu has been voluntarily guarding the martyrs’ cemetery for 39 years: I am their relative. Ji Houjun prune pine trees and green plants, and paint red and wipe the tombstones of martyrs.

"The five-pointed star is the cap badge, which represents the image of a soldier, and the red color represents respect," he said. He often goes to schools to give voluntary lectures to let students understand the heroic deeds of the Shuanggou martyrs in the Battle of Shuangming.
