Introduction to the front office of the branch: The front hall of the branch uses a large number of well-preserved objects and photos to show the audience that before and after the Battle of Laiwu, the people in our liberated areas followed the troops in large-scale migration and provided supplies for the troops in order to win the battle. The numerous heroic deeds performed in the frontline operations such as rescuing the wounded, rescuing prisoners, serving as guides, etc., reproduce the deep affection between our soldiers and civilians during the war, and reflect the glorious tradition of the people in the old revolutionary areas supporting the army.
