话说三国时期，蜀汉名将赵云在长坂坡单骑救主，面对曹军百万雄师，他丝毫不惧，挺枪跃马，匹马当先，杀进曹军阵营，七进七出，最终救出了刘备和阿斗。赵云的英勇表现，成为千古佳话，也使得“匹马当先”这一成语广为流传。
During the Three Kingdoms period, the famous Shu Han general Zhao Yun single-handedly rescued his lord at the Battle of Changbanpo. Facing Cao Cao's massive army, he showed no fear, and bravely charged into the enemy lines, rescuing Liu Bei and his son, A Dou. Zhao Yun's heroic actions became a legendary story, and the idiom "pi ma dang xian" became widely used.
