"Get on the horse and meet the enemy, get off as brothers" is a classic old saying, which is used to describe unity and close brotherhood. "Mount the horse * * * to meet the enemy" means * * * to face the enemy on the battlefield and never give up; "Getting off the bus is brothers" means that in our daily life, we are close and brotherly. It is emphasized that brothers should support each other and trust each other whenever and wherever, and face the challenges and difficulties of life together.
