In June, the humid wind of Heshun Ancient Town, carrying the dampness of the bluestone slabs, made me sweat. As a military enthusiast obsessed with the history of the War of Resistance against Japan, and having watched "My Chief and My Regiment" more than a dozen times, this trip was not sightseeing, but rather following in the footsteps of the cannon fodder regiment to touch the tragic heroism and perseverance hidden in the everyday life of Chanda. I stood under the old locust tree next to the Heshun Library, my fingertips tracing the mottled patterns on the trunk, and images flashed through my mind like a movie: Long Wenzhang's madness and clarity, Meng Fanle's stubbornness and soft heart, Mi Long's irritability and deep affection, and those cannon fodder soldiers in the refugee camp.
