Introduction to the evergreen tree: The evergreen tree next to the monument is the tree that General Yang Jingyu leaned against when he died heroically in the heroic battle against the Japanese invaders alone on February 23, 1940. The original tree was a "twisting tree" The tree later dried up. In the 1960s, this coniferous pine tree was planted here to commemorate the general and was named Evergreen, which means that the general is an evergreen conifer and will live forever in the world.
